Hi,
you should consult the Serena Teamtrack admin and users guide but I believe that you can browse, list and even sort by projects.
I went and looked at the http://knowledgebase.serena.com and found a reference to browsing and listing projects, although I usually just browse the file system myself but that is also because I like to understand the internals of these tools :-)
I will tweet this question out and see if we can get a few others to respond as well.
