The scrollbars in Unity are too thin and this makes them *very* fiddly to use because it's hard to position the mouse pointer onto the scrollbars. Attempts to move the mouse pointer over these thin scrollbars means you can easily miss and end up too far left or right of the scrollbar itself.

This problem is even worse with some brands of computer mice which operate very fast when plugged in!

Unity is gaining much popularity over GNOME and so are Unity Lenses, With the Advent of so many Unity Scopes and lenses it would be rather helpful if One-Place Manage for Unity lenses be done

What would be great for future versions of unity would be an active notification center that ties in all the apps available for Ubuntu...Much like Android,iOs,and Windows "Action Center" I and most likely other user often experience an odd and uncomfortable lag in the notification blob... it will sit there on the top corner unobtrusive until you try to interact with it and that is when the problems arise whether it be from a broadcast update or another applet it will remain there longer as an opaque addition to the screen
.Instead i suggest a small applet that springs open"like an app that need attention on the unity bar" that can easily be dismissed and viewed later in one place

Actually, nowadays I'm using an old version of Ubuntu (10.04), since it's the latest one which I can configure both nvidia cards in and its respective 2 monitors. These settings must be set on the nvidia-settings app. The main problem is the null support with unity or gnome-shell, supposed to be because of the old incompability between Xinerama and Composite. I'm only able to arrange a non-composite desktop with 2 twinviews, so maximize the windows will occupy 2 monitors. It would be useful to have the possibility to maximize in one or two monitors. I don't know how to do it and where the problem comes from, but these are my needs.

Canonical and the community need to find a solution for people that use their computers for business and productivity to have quick menu access for windows on a multi-monitor setup AND windows that aren't currently active.
There are several problems with the current application menu system used in 11.10, as well as 11.04, and 10.10 Netbook Edition: The user can only have one application menu open at once and the top bar doesn't stretch to the next screen on a multiple monitor setup, which means the user has to go to the default #1 monitor in order to access the application menus, which can be annoying to the user, and waste quite a bit of time in the long run.

PS: It's a lot of the "big things" (like OS crashes and major annoyances) that matter in making Ubuntu an easy-to-use, efficient desktop OS or not, but a whole bunch of little things (like application menus and minor annoyances) can be worse than one, two, or even three big things. It is my duty to take on these challenges, one-by-one, as I see fit. If we, the Ubuntu community, take on all the challenges we possibly can, including big and small, we will see a much nicer, efficient, fast, stable, usable Ubuntu for everyone.
