There's a lot of focus on usability, accessibility and user experience going on. I recently wrote about the clutted Nautilus sidebar and how categorize items displayed with headings would make it easier to navigate, providing a better user experience.
I also wrote about the new notification feature in the upcoming Ubuntu 9.04 and how, the new plasmoid, the KNetworkManager component recived a very slick and refreshed look for KDE 4.
It seems there's a lot of good stuff coming, that will make many tasks easier.
Today I created a Ubuntu Brainstorm idea and added the mockup you see below:
As you can see above, a new option has been added to the Appearance Preferences menu. You can choose between different background as you always could, but now you can multi-select pictures. Multi-select works by CTRL-clicking each item you wish to include. Multi-selecting pictures will create a slideshow on your desktop background. I hope this will provide a better user experience, though this feature is something most of us can live without. I have no idea how this can be combined with my expanded wallpaper for multiple desktops idea.
The idea is awaiting moderator approval before going to the popular ideas area, but when it does, cast a vote here:
