For usability, I propose that there should be icons of the programs that is displayed in the context menu when right clicking a file.

If I right click a deb file, for example, there is a line that says "open with archive manager", and one that says "open with package installer".

I think that it would be nice if there were also icons next to the names of those programs.

Well, to many people, Linux is still equal to complex CLIs.
Many people still don't know much about Linux, let alone Ubuntu. Some are quite reluctant to make the first step(towards embracing open-source, fully, or partially).
Some feel a bit lost since they are new to the Linux environment.

Apparently there are many developers out there who'd love to code something but they don't know what to code.
On the other hand I've encountered several times the situation that I'd need a little tool to do a small task but sadly I cannot code.
As posted there http://ubuntuforums.org/showthread.php?t=807085&highlight=programming+ideas&pag e=1 it seems as if it was quite hard to find good ideas at all and, to be specific on Brainstorm.

I know this is a very small thing to suggest, but the fog/mist icon used by the built in Ubuntu weather applet is VERY ugly.
The square icon looks out of place, and whenever I see it my first though isn't "oh look, fog" but rather "great!, why isn't my weather applet working" -- It looks more like an image isn't loading then a representation of the current weather.

Again, I understand that this is a very minor issue, but it should also be very minor to implement (provided others agree about the icon).

We all know there are some corking great bugs in Ubuntu, some real honkers and it's quite galling to see release after release come out without addressing them. I won't go into specifics as that will get this post labeled as a bug report and directed to the bug tracker where it will promptly be ignored forever.

You see this site is quite symptomatic of the problem, bugs are swept under the carpet and the spectrum of allowable thought is limited entirely to new features. The sad fact is many existing features are incomplete or unreliable.

Personally I couldn't care one jot about the obligatory new theming every 6 months, I neither want nor need an "app store", "music store" or "cloud drive" and where the minimize and close buttons go is IMHO a triviality.

What I do care about is seeing massive bugs persist in core programs and components from release to release. Some of them are bad to the point of embarrassing and I would far rather have attention and resources directed at them than the latest shiny spinning gizmos that nobody asked for.

The biggest problem open source has is that developers seem to abandon products when they are 90% complete i.e. just good enough to get work done in. That last 10% may not look like much but it makes a world of difference so if Mr Shuttleworth et al really want to take a leaf out of Jobs' book this is where they should be concentrating.

Not all users have unlimited computer resources, be that hard disk space, memory or volume/bandwidth limitations with their ISP. The Ubuntu Software Centre does not report the download or installed sizes for packages, yet these statistics are available for every package. (have a look at apt-cache show for any package)

Icon keyboard layout does not look standard Ambiance and Unity.

The current icon was made before the software center was renamed from software store. It is based on an image of a shopping bag, which was appropriate for the store but is no longer relevant.

A single unified tool should be provided which allows the user to connect to a network (or internet) via any supported method. It would also be useful to provide an extension to this tool to manage firewall rules and network connection sharing.
