I found the current changes in Blender’s UI and related features rather odd.
First, the removal of layers and the related hotkey to access them. It’s a quite unique feature that I’ve only seen in Blender and have been fondly using for years. I like how convenient it is and the degree of freedom in visibility control it provided. I understand we have collections now, but…
Secondly, the re-assignment of number keys for mode change. Did they really removed Layers just for this? We already have a flawlessly working pie menu feature that IMHO is perfect for mode changes and a completely brilliant idea in how to assign hotkeys and macros for most of the functions we use in Blender.
Yet, Pablo just said it was “weird” to have pie menu to select modes in today’s Blender live stream. Why? I’ve been using pie menu for mode select for years and even with different object types, it hasn’t been an issue at all. But rather working extremely well. I don’t understand the change. The options for different types of objects, if they don’t have a “pose” mode, the option simply won’t show up. Which is just the way it should work, isn’t it? I can’t accept the change to use Number keys for mode select when we clearly have better options already.
Unlike the un-labeled shortcuts or hotkeys, pie menu shows the label for all the modes, too. Hold key, move mouse in general direction and release key will execute the command. Doing it fast enough and it is as quick as press of a button. It’s both more intuitive and more efficient than 10 number keys for mode change.
And then… Someone pointed out the use of spacebar as a modifier key. (I do, and I use spacebar exclusively as a modifier key). Currently, 2.8 use spacebar to call up a menu, and you can then press G, R, S to transform objects… Why do we need to press spacebar at all?
Nonetheless, there are quite a few good changes, too. I hope everything can come together nicely in the end, but definitely not how it is now.
