I hope I am posting this to the right place. Here are a couple of things that would be really helpful. And if it can be done already, someone please let me know how:

Filters: When I am in contacts or organizations, the filter only searches the contact or org. name - not their whole entry. So I can't do a quick search for an organization in a particular city, for example. When you use the search while linking, it can do this.

Writing a Letter in Projects: There is no way to choose which linked contact to merge a letter with while in projects. See this link for further discussion - http://forums.marketcircle.com/eve/forums/a/tpc/f/6441090623/m/3051047715
