Short description of related/example of what I mean:
When you first log in and haven't yet selected a project, and you click on 'Browse Project', you are presented with a list of projects to choose from. Once you actually choose a project, then the 'Browse Project' link remembers your 'current' selection (I'm guessing it's in the session). To get back to a list of ALL projects, you'd need to click the "Projects:" link (In front of the project name on BrowseProject.jspa) to get a listing of all projects.
So how about 'Find Issues' using the 'current' project in a similar way? The reason this would be kinda cool, is that right now, if you have custom fields within your project, you can't search on them without first choosing the project and doing an initial "throw away" search first.
After the project is 'set', the custom field for that project does show up at the bottom of the left column. But if we used the 'current' project then we wouldn't need the throw away.
