Wouldn't it be nice to be able to flush all the junk stored in nautilus after you opened a folder with 5000 pictures or videos. All that space is still taken up after you leave the folder. I know you could just kill the process and restart it in terminal, but shouldn't there be an easier and automated way of doing this. I suppose a threshold could be set at 100 megs and after nautilus uses that much the system will automaticly flush it. A simple run time script is capable of solving this, a manual option to wipe memory clean on a scheduled basis could also come in handy as well. This program could later be expanded to flush garbage out of other parts in the ubuntu system. The all time record size of nautilus for me has been 1.4 gb, I kept it running for 7 days straight. Everyone reading this should submit their all time record size as well.

I'm not a huge fan of Windows restore points as a cure all for OS issues, but there have been times when they have saved me, and times when I wish that I had them for Ubuntu. For example:

In my first Linux en devours, Compiz-fusion didn't just work. (Thanks for that by the way!) So one would have to edit the xorg.conf file. As a novice I copied and pasted from a forum, and it entered ASCII blocks instead of the needed quotes (""). When I went to restart Ubuntu wouldn't load graphically. I didn't know that you could dpkg-reconfigure that file, and nearly pulled my hair out.

I would also like to see a Previous Versions option for folders in case you accidentally delete a file while holding shift. I sometimes do this knowing I'll never need that file again and later I will.

You should be able to report a bug by just emailing a support address.

Yes, I know that all I have to do is:
1) Register an account on launchpad
2) Check to see if it's already been raised
3) Raise the bug if not

But: step (2) assumes some technical knowledge, I think, and the whole process assumes that you will willingly join in the process of testing, debugging, and fixing.

I would be the first to laud the whole "all of us in it together" thing, because I'm a Linux nut. But if we really want Ubuntu to be an OS for the people, don't we also have to consider the people for whom this is not practical or desirable, because they lack the expertise, the time, the confidence, or just don't play well in groups? I think we do.

I've noticed it takes a lot of time when browsing to the most popular week/month/ever pages. Also, clicking through to subsequent pages (page 2/3/4/etc) is slow.

The live CD is the first thing many people see when trying Ubuntu and it can be a turtle even on the best systems. This is hardly putting our best face forward.

The Live CD needs to be better optimized for responsiveness to make for a better user experience.

Addendum:

The constraints of a Live CD are hard to work with especially all the different hardware out there. I think with the Live CD less is more.
Most people that take it as a test drive are going to look through the menus for things that look familiar to what they know and try browsing the net. For the most part they are not going to be doing anything intensive. I think one option is reducing the memory footprint and services loaded. I'm sure there are other suggestions that you and the developers may have.
