When clicking "Browse project" the URL is say http://jira.atlassian.com/secure/BrowseProject.jspa - although the actual project showed depends on where the user currently is.

This non-REST-ful URL is not bookmarkable and I can't send it an email to anyone. If I have two tabs open then everything gets messed up as there's two current projects.

It's not easy to figure out how to get the corresponding BrowseProject page for the actual project (ie. http://jira.atlassian.com/browse/JRA ).

The link for "Browse project" should go directly to the specific URL ( http://jira.atlassian.com/browse/JRA ) - and the BrowseProject.jspa URL should redirect to /browse/$currentProject.

(In general those .jspa URLs should be avoided, I guess..)
