I absolutely L-O-V-E the dynamic workspace management from GS, specifically with the Desktop Scrolling extension.
- I like both the Unity and GS panel. Both are configurable, feature indicators/extensions. I like the Evolution/Calendar integration in GS panel. Preferred location for panel: top. I like your idea very much as well. Does what it should do and provides necessary and essential information. Also the notification center looks great!
- I like the Unity Dash a little better than the GS overview: Dash seems a little more intelligent with the lenses and less disturbing my view. Though both can be used quite efficiently (hit Super and start typing to search). I also like the Win7 menu, which effectively does the same. I think this (press Super and start typing) is a key feature for an efficient workflow.
- I like Unity's Global Menu; in general the idea of a global menu. But not Gnome-shell style (too many clicks to get where you want to be). I also (as in a reduntant, keyboard-only way) really like the (idea behind) Unity HUD, but it isn't quite mature yet. Biggest annoyance: the naming is inconsistent so it takes too many tries to find what i want. Example: I want to change some settings; randomly start guessing if it should be options, settings or preferences (and if you also have translated programs: opties/instellingen/voorkeuren). So you might need to search for 6(!) different keywords.
Suggestion: let it display the currently accessed menu structure and all avaliable options. So when you type 'Edit ' it shows all available items in the Edit menu. Or a combination with the (normally hidden) global menu can be made. But most important of all: consistency!
- I like the Unity launcher/bar, especially the full (non 2d) version. Nice look and feel, location on left edge is fine to me. Icons are large enough and size is configurable. I liked the intellihide mode... Other launchers can be fine too (i.e. Docky)
I dislike the Gnome Shell launch/favorites bar (and extension to get it on the desktop): with a lot of applications opened the icons get way too small. Also not too much animation/information from the icons, which other launchers do.
