1. iphone support for basecamp
2. CRM for customer management
3. Status updates to log the progress of pending to-do lists, general tasks and milestones.

All in all, I heart Basecamp – the most easy and productive B2C, B2B collaboration tool I’ve come to love!

I definitely second iphone support. I just got basecamp, and came from RTM. You should just partner with those guys, they have the iphone thing seriously together!

iPhone support would be HUGE!

Hi all – I am not sure if you are still following this thread, but we just added simple Basecamp todo functionality to Treetop. Treetop is a Basecamp extra that integrates with your account via the Basecamp API. You can check out the screencast here. Please let us know if you like it! Thanks – j
