I am starting this thread for fun, but also to help the community a bit :
write down what you find most absurd in blender, regarding it’s features, completeness, compatibility between editors, UI , code structure, API, e.t.c.
Please DON’T DISCUSS in this thread, it’s supposed to be a list which is readable. So, don’t react to what others write, if you want to do so, start a new thread, please. If this thread gets messy, it won’t be usefull to anyone.
This list can maybe draw a bit some image of how things could be put more together. It is in no way inteded as a way of complaining to developers. The idea behind it is to get ideas from it, about small things that could be improved.
Put your idea into shortest as possible formulation!
Don’t put any frustration or anger in your post.
THE LOG STARTS HERE:
You can unwrap UVs in 3d view, but you can not unwrap in the UV editor, if there’s no UV layer yet.
You can mark a seam, but not unmark it in the UV editor.
