Operations involving network access were written to be non-blocking from the beginning. So making them blocking was a choice - to avoid having to deal with additional issues users managed to find, although I never liked it being blocking.
Committed support for non-blocking operations.
Thank you! Much appreciated! 
Before you do anything like this, please read up on how to do it properly from ethical perspective. There are articles online which describes how security researches can do experiments like this without causing disruptive harm.
I also suggest read up on the University of Minnesota and Linux incident, to understand why following those commonly expected protocols is important.
Is there a reason why this
is shown and then this
appears after the first one is clicked? Wouldnât it make sense to just directly show the second one?
Is there a way to show only legacy addons installed by me? Since legacy is the only way to install paid addons, I need a clean way to list those installed paid addons to check out for updates. Currently extension iteration doesnât allow it? Iâd like to request for adding filter that does do that. I also would love to have âinstall from diskâ button on main interface, instead being hidden by dropdown menu - most advanced blender users rely on paid addons and I think current extension platform GUI is leaning too much towards free extensions.
EDIT: showing only addons installed by me was possible in 4.1 and older versions - I really need a simple listing of those addons to see what addons I have and manually check on their websites/githubs if there were updates in meantime.
I think current extension platform GUI is leaning too much towards free extensions.
Not just free extensions; it leans away from anything that is not on the extensions website.
Perhaps itâs improved in the latest alpha; the last one I looked at a few days ago seem to be just a random collection of things. It felt like the software was trying to punish me for using add-ons that were not coming from the extensions website⌠A virtual âHow dare youâŚâ
Am I mistaken on thisâŚ? Is the Extension pref tab now showing me EVERY SINGLE EXTENSION thatâs on the extensions website?
Somehow, I thought that the plan was for one to browse the Extension website, pick what I might want. After installing, it would be added to this list. Iâm seeing things in this list that Iâve never used and will never use. POV addon, Export Paper Model, something called âForts Map Importerâ which apparently relates to some Steam game iâve never even heard of.
Eventually this prefs page will scroll for daysâŚ
And on a related/unrelated note:
âŚ
No, I donât.
I think itâs fairly obvious that âsort alphabeticallyâ and âshow only enabledâ are not the same thing
Not what he said though, he said âsorting by alphaâ and disabled extensions are dimmed, i can easily see how @filedescriptor got there, so perhaps things are not as obvious as they seem and spending a little bit more time explaining the problem that is seen seeing and explaining how people think it should be solved, wouldnât be a bad thing.
âis this what you meanâ, âNoâ with no further explanation, is also about the least productive way one would get their ideas implemented though.
There is work happening in this area:
Honestly, it felt like very little effort was taken to read my post, take the full context of the situation, and ponder on it for a moment.
I could have typed âno thatâs not what I mean, please read my post againâ⌠But I have a feeling that would have come off as unpleasant.
Get outta hereâŚsomeone read your post, didnât understand what you were trying to say, but hey, this is the internet, misunderstandings happen, thought he saw a way to help, took the effort to make a screenshot even highlighted the checkbox he thought may help, and you took all of this as âlow effortâ ?
My suggestion was to do a better job explaining the issue, not superficially increase the word-count by adding additional unpleasantness, cause that we indeed could do without.
Everyone please keep things constructive and polite (and on topic).
To the question âŚ
Is the Extension pref tab now showing me EVERY SINGLE EXTENSION thatâs on the extensions website?
It always did. The âdiscoveryâ (figuring out which extension you want) is possible from within Blender, as well as from the respective repositories.
After installing, it would be added to this list.
Do you mean this ?
Either the âEnabled Extensionsâ or the âInstalled Extensionsâ would indeed prevent you from being overwhelmed there. As Brecht pointed out, this is also tackled by the changes to bring the Add-ons tab back.
Is it possible to access the same repository from different accounts simultaneously?
E.G. I have a personal account and a company account on Blender Market; can I access to all the addons purchased on different accounts?
Hi!
Iâve tried the beta after the split between extensions and add-ons, and I have some feedback. For reference, now, Extensions and Add-ons are split in two sections:
As far as I understand, the logic behind this split is the following:
I think there are some issues that are very confusing:
I see why this was done: because extensions can also be other things (themes) and because you want to split the âstore explorationâ logic from the âadd-ons managementâ one. However, currently, it is definitely weird.
Can I recommend taking a look into probably the application that pioneered extensions, Firefox? It is quite clear. When you click on âAdd-ons and themesâ from the main menu, you end up here:
I think this is similar to what youâve done, but its naming is clearer.
What I suggest is:
Moreover, I think Install from Disk should not be in a hidden tiny menu:
Can you add a button for it? Itâll probably be the most important button for users in that whole section. Hiding it like that almost feels like hostile architecture 
I hope my points can be useful.
I respectfully disagree with your line of thought on the new format for the add-on tab. BF listened to feedback and gave us what everyone was asking for⌠to split the manual installs and listing of add-ons away from the Blender extensions website repository tab. It doesnât make it confusing, the first implementation was what was confusing. You can now install and filter everything you have installed from the add-on tab just like the âold schoolâ way. Added bonus is now you have the extension tab to search the extensions from the BF extension repository separate if you want to go that route. This is actually now a cleaner add-ons tab compared to the old school way. I think naming the add-ons tab to something else would just confuse things even more. If anything maybe name the extension tab to âextension repository.â
The new format is now inline with how it was with the older add-ons tab with form and function minus the install button and the clutter of unwanted add-ons. You can still install add-ons from the add-on tab now just like the old school way, minus there being an actual button for it (see image). You donât need to install âlegacyâ add-ons from the extension tab.
I do agree we should have a visible install button like in the older add-on tab. But as of right now this almost matches prior Blender add-on tab function with the extension tab now being separate. 
Perhaps, but in the context of Blender:
An addon is a plugin for 4.1 and earlier versions.
An extension is a plugin for 4.2 and later versions.
They are two different things, with different scopes on how to be easily installed, updated, managed, etc.
