Usability niggles, Ubuntu

Ubuntu's next release will have one hundred paper cuts as a focus - fixing usability issues for users.

Here's my best pet peeves.

1. On windows, if I paste in a URL in an "open file" box, windows will fetch it for me, write it somewhere temporary, and give me that temporary path. Gnome is inconsistent - I can put a URL into a the 'Run' dialog, but gedit doesn't let me open it. However, if I start gedit from the command line, it will open it - gedit https://edge.launchpad.net/hundredpapercuts/
2. 'Choose another application' when opening a file from firefox gets me to try and look around for the path of an application. As a newer user to linux, I often have to fall back to the terminal, and use things like 'which gedit' to get the right path. If the run dialog can work out which application I want, why can't firefox.
3. With gedit, if I open a file which does not exist, it does not let me create said file - it just errors at me.
