Comment 3 for bug 794410

Wow, it's been a while since you posted this, sorry for not responding sooner, and thanks for the suggestions!

The Close button has been moved to the right, but I'm not too sure about the reordering of the sidebar entries/tabs, and I don't really like the "Wine prefix" suffix - it looks a bit clumsy to me.

The reason I moved things to tabs was to keep the amount of entries in the sidebar low, to not overwhelm new users with too many options at once, but you might be right that it's a bit tricky to navigate.
I'll try to do some mockups of the sidebar as you suggested, but with separators - something like this maybe? :

General
> System
> Folders
Appearance
> Windows
> Theme
Devices
> Drives
> Graphics
> Sound
Programs
> Installed
> Available
System
> Libraries
> Tools

Let me know what you think, and thanks again for the suggestions.
