Ubuntu should maintain a database of programs for different file types, so that instead of clicking a file and discovering there is no supported program installed.. Instead, they should be prompted with something like the following:

=======================
- There are no known programs installed to open "jakebox" files.
- Ubuntu can install one of the following programs from APT automatically. We believe they may be able to open the file: (Show packages: eg. KJakebox, JB)
- Or you may select an existing program to attempt to open it with. (Show existing program list)
- Or just cancel
========================

This would be integrated with synaptic and catch all unsupported file types, and means that even advanced users wont have issues opening files they have never seen before.

I think all hands would be up on brainstorm when i asked if people have at least once been sent something they had to google to work out how to open.

Originally, i was really against the idea of a dark theme, and maybe i'd still prefer it if Ubuntu would lighten up a little. I understand the organic theme completely, but please...this is an operating system. Anyways, all the dark themes i had seen really turned me off and even the best ones seemed to be loved by some and hated by others. If we're going to have a dark theme, lets have one that we can all agree on. When i saw the Intrepid alpha screenshot, like many others, i gagged a little.

How people interact with their computer is really essential to their satisfaction. This is why aside from features, the software's stability (minimizing annoying bugs), speed (clean code and making everything as efficient and responsive as possible), and interface (look and feel) are the three most important things that should be our focus and be kept at a high priority.
We should really work to increase usability: http://mpt.net.nz/archive/2008/08/01/free-software-usability

I have looked through all the artwork submissions for Intrepid, and of all of them, this is the one dark theme that i would actually like to use: https://wiki.ubuntu.com/Artwork/Incoming/Intrepid/Wall-light

I first saw it on this Digg submission: http://digg.com/linux_unix/Intrepid_Ibex_Mockup_Designs

Of course, i'm sure everyone will have input to make it even better. This isn't a final design, but vote for the concept so far!

P.S. Please Digg :) Thanks http://digg.com/linux_unix/Vote_for_a_beautiful_usable_Ubuntu

gnome-system-monitor provides a cleaner interface than Windows "Task Manager", and provides many useful features including list of processes running, memory and network usage, etc.

This functionality should be more accessible by key binding it by default to CTRL-ALT-DELETE as Windows does--as this is more familiar to users coming from Windows. The current key binding for CTRL-ALT-DELETE brings up the shutdown/logout options, which is already accessible as a desktop button, which is redundant for a relatively less used function.

gnome-system-monitor is an idle interface for monitoring the system and killing processes without using the terminal and provides an interface for doing this that most are already familiar with. Changing it's key binding would make it's functionality much more accessible.

I don't like my username being on show to the world. Having my name in the corner is a much more personal touch, as it was in Jaunty. Plus it looks more professional when using a projector and such.

Because it's not easy to use Ubuntu (Netbook Remix) 9.10 Beta on a laptop (no mouse plugged in) with this option disabled - I can't perform (emulate) left mouse button click by double tapping the touchpad area.

When an external NTFS hard disk is not cleanly unmounted because you unplugged it wildly on Windows, or because of a Windows crash, there is an error when you try to plug it on ubuntu, explaining what to do on the command line.

There should be an easy way to mount the volume anyway, by giving the choice to the user to mount it anyway, or not to mount it. A clear dialog box should do the trick.

Every application treats file size units in a different way so you never know the real size of a file or a drive. I.e. my USB device shows up as 4.1 GB when mounted on my desktop, but as 3.77 GB in GParted, while the system monitor gives me 3.8 GiB - that's confusing!

Actual Human theme is incomplete, some applications use a icon with large size.
Not only new applications like Gnome-do
"Search-gnometool" of gnome use a large icon, nut it isn't so sometimes use a little icon, or other use a default theme of gnome.

This is a problem that affects practically anyone who enjoys tweaking his desktop. Sometimes, the background color (or texture) one chooses doesn't go with the window theme's font color. The problem is that it is not yet possible to change the panel font color by right-clicking a panel and choosing "Properties". Instead, one must create a file on his home folder and insert some code, on which he must inform the RGB code for the color he wants. Altogether, it is a very complicated procedure for anyone who's not a geek, which definitely detracts from the user experience (one of the main foci of the Ubuntu devs).

Nautilus could detect if a folder contains a majority of a certain type of files and adapt the type and number of columns to provide more useful details.

I think of pictures folders, where it could show exif informations about pictures like the resolution of the picture and its capture date (in addition to the modification date)

I also think of music folders, where it could show the bitrate,the length and the (ID3) tags of the music files.
I think this would be very useful.

In addition, the ability to add/remove columns should be available by the right click on the listview header.

Please see the comments for further ideas

From #6245 (merged):

Having an extra column in the list showing something like "23x456" would be ideal, because you could see the info for all the files in the folder at once.

Have the info in the status-bar would be better than what we've got currently (right-click->properties->image shows the info in Nautilus, but it's not very efficient)
