This will make it easier to know which projects they are associated with from the Global Calendar

similar to the documents and designs, it would be great to have discussions separate for tickets

It would be nice to allow a client access to see the calendar, task status, etc... but without the option of creating a task or running reports. You get the idea.

Examples of hosted sites that provide this service are:

http://www.codebasehq.com
http://ww.unfuddle.com

Would be great to have it all integrated.

I'd like the option of a setting that allows the presumption that I want to see my lists in "expand all" mode. As it is, I'm having to expand over and over and over again; and it drives me nuts.

Ability to create tasks outside of projecturf directly from a new created or even forwarded email.
