I've observed in my job that most of the users forgets to empty their trashes regularly, and suddenly one day they start to have problems due space limitations, or they don't know where is used their hard drive space.

I've got two monitors, and right now if I use the wallpaper settings in gnome it stretches the wallpaper across the two monitors. It does this even for the default ubuntu wallpaper. This can look really bad depending on the image. In order to get around this I had to get two wallpaper images and join them into one large one with the GIMP and set that as my wallpaper.

There should be a way in gnome to set a different wallpaper for each monitor.

==== Merged with ideas of a similar scope: Different wallpapers on different workspace ===

Many workspaces option in Linux allows you to separate your work, why not allow users to have different wallpapers on each workspace. This allows for easier identification of which workspace you are on.
When used with compiz-fusion you can rapidly switch between your workspaces and the different wallapaper will allow you to quickly recognise what desktop you are on.

Currently this is natively available in KDE but not in Gnome. In Gnome you can't even let Compiz take over the wallpaper control because Nautilus doesn't allow for transparent backgrounds.

Other solutions like Wallpapoz are slow and when switching between desktops it takes too long to switch WP.

Some Ubuntu users have PC or laptop - for example UMPC - with small hard disk size. They needs more disk space than hard disk performance. For example Microsoft NTFS support compressed filesystem, so it can save 10~30% of space.

Why Ubuntu don't introduce a such compressed filesystem? There are already some compressed filesystem which can use on Linux.

I hope Ubuntu support these filesystems, for users who want to save their hard disk space.

these are ideas or suggestions to improve new notification server or message indicator usability.

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.

In Nautilus, when browsing in Icon View, it is currently impossible to distinguish between document types that provide previews without looking at their file extensions.

For example, if I have 2 similar documents side by side, one is a PDF, the other is an OpenOffice Writer document, they both look identical and I cannot tell which is the PDF without looking at the file extension.

See here for an example in Ubuntu 8.10:

Solution: Add a visual cue to the preview icon (either a mini file-type icon (like Windows), or simply a watermark with the file extension (like Mac OS X).

Windows and Mac examples:

I think this would be great for everybody, because OpenOffice 3.0 has A LOT of improvements that will help people that uses this kind of program constantly to migrate from MS Office to OpenOffice.
Support for MS Office 2007 documents and PDF editing are two good examples.

I know that Intrepid will be released in 15 days, but I think there aren't going to be a lot of crazy bugs to be fixed in "only" 15 days by developers if this program gets upgraded in Ubuntu repositories!

Think about that and let's do this now, instead of waiting more six months (Ubuntu 9.04) just to get this great program by default... you know, if more good programs comes by default, more the newbies and veterans will like!

Gimp needs support for 8, 16, and 32-bit per-channel images like Photoshop does and Cinepaint (http://www.cinepaint.org/ ).

People who use wubi install to try the system would benefit from a tool that would make it easy to migrate the install to a native (partition) install.

Background:
I like the idea of drawers for the gnome-panel (except for their slow and buggy nature). I think that something like that should also be available to power-users for the Places Menu.

There is, in fact, something like this already in place: the Recent Documents folder on the Places Menu. I think you should be able to make custom folders, like the recent documents folder, that have some of the contents visible on a side menu.

However, the Recent Documents folder lacks one function I would want for drawers in the Places Menu: clickability. If you click on the words "Recent Documents", nothing happens.

So with all of that background out of the way, here's my idea:

A Drawer option for the Places Menu with customizable contents and clickability.

Here's what you'd be able to do with that:

Let's say I make a drawer out of my "Documents" folder in the Places menu.

1) I right click on the Documents drawer in Places. I choose "Turn into Drawer" (or whatever). I then check the boxes next to "Pictures" and "Music", all of which are subfolders of "Documents". I leave the "Videos" folder unchecked because I don't want it to show up in the drawer.

2) I close the dialog. Now an arrow appears next to "Documents" in the places menu. If I click on "Documents" it still opens the Documents folder. No change in functionality there. However, if I leave my mouse there for half a second, the drawer pops up with the selected files listed. I can click on them to open them.

3) Theoretically, I could right-click on one of the folders in the drawer and turn it into a drawer as well.
