Thanks, don’t worry too much about apoligizing to @LudvikKoutny or anybody else for that matter. He likes to talk like he’s coming from a place of authority and knowledge, but last I checked he’s just a guy who started this thread, and then complained enough times in a rude enough way to get it locked.
As far as this:
If they found one additional toggle complicated, what makes you think that multiple toggles scattered all over the Blender’s UI, partially in tools, partially in preferences, will change their mind?
That is his usual way of doing things. Either exaggerating or taking things out of context, because he thinks that it will somehow result in everyone agreeing with him. Careful though, if you try to reason with him he might call you names 
This is what I’ve seen said from @ideasman42 about kio’s patch
This feature seems error prone, since it’s not obvious when it’s enabled and you don’t see the geometry you’re selecting.
Even in the case when the user knows this is enabled, there is some chance for accidents - as the result of the selection may be unexpected, any tools that run afterwards may operate on an unexpected result.
This interferes with edit-mesh drawing, removing face dots so it’s not clear if you’re in face select mode or not.
While it displays as a tool option, it’s always used even when the tool isn’t active (running selection commands from key bindings).
Seeing as we already have toggle-xray (Alt-Z) which enables this behavior while showing the resulting selection, I don’t think this is necessary.
If there are some deficiencies with xray display, these could be handled separately.
This is more a design task.
I do not interpret that as “Select through is too complicated.” or “I like this, but please don’t add any more features to it. Especially if they attempt to address the issues I have with it.”
I see this as saying:
- Select through is too accident prone no matter the context
- It isn’t clear to the user when select through is on
- Don’t just turn off facedots because it’s unclear if face select is on
- Xray works good enough, so we can address that in another way if needed
I’ve said this a few times, and I do not mind repeating it, so please bear with me if you have heard it before. I don’t think there’s any convincing to be done with this feature. The devs could have select through if they wanted it, but they either have their own plans for it or none at all. I’ve been asked by a few people in this thread to submit it for review, so I figured why not, I might get some help with a few things that aren’t working right. Not likely to happen but the effort is minimal.
I didn’t bother removing things and separating it into different diffs, because I’d like to hear what, if anything, they like about it.
I don’t like to play internet janitor because that isn’t my style, but it comes with me asking the thread to be reopened. If you want more of a summary than that here you go:
Ludvik wants the original patch that kio made, because it’s good enough as is. I agree with him. I made the patch faster, and he is benefiting from this effort. It doesn’t stop him from complaining about it though. I have added features to give other people things that they find useful, myself included. If you don’t agree with him 100% and do everything he wants, he will act like you are the unreasonable one and try to insult you. Or he’ll say the devs are intentionally ignoring this feature request, which is just a little too entitled and childish for anybody to entertain.
Nothing I’ve done stops him from using kio’s patch, or my patch in the same way, but he just can’t help himself. He is our special friend who you help out from time to time, with the expectation that he will find some way to cry about it. My favorite is when the devs didn’t immediately add the faster version of kio’s patch that I made to Blender, he tried to threaten us all with leaving Blender forever because he has to spend some exaggerated amount of time and effort compiling a couple times a year. Or maybe he did that before the faster version, I dunno, still really funny either way.
When people aren’t having to explain to Ludvik why it’s ok for others to have their own opinions and needs addressed, and that they aren’t mutually exclusive with what he gets out of this patch, it is a useful enough thread.
