I think sometimes you use the word "bug" too lightly, but thank you for reporting the problems you see.

Let's say you don't like how this works

This one I cannot reproduce. I always work connected and that premise alone does not lead to your conclusion, I think.

Regarding the modifiers list: agreed and I would add more things; noted down. This would be an improvement more than a bug, though.
Regarding the issue with the Texture List, I cannot reproduce it. In my case, non used textures do not appear in the list; if i delete an object its related textures disappear from the list if they are not used anywhere else. If the texture has the same name but it's in a different folder it's considered as a different texture (because you could have two "black.jpg" textures in different folders that actually are different); the texture that shows as "not loaded" probably is corrupt and cannot be read for some reason.
Regarding the problems with the UV sets, many things were fixed in 18.104.22.168/22.214.171.124, so I would suggest to update.
Regarding the problem when the computer goes to sleep, well, if the OS is stopping the graphics card, the OpenGL will not responde; I'm not sure if it's even possible to recover from that. Probably the same thing will happen with a video game. In windows you can specify what is disconnected when the computer goes to sleep, probably if you don't allow the OS to disconnect the graphics card, it won't happen.
