I have used Basecamp for a few years now and even though it does the job there are several things that let it down for me.
My problems with Basecamp
The one thing that sits right at the top of my wish list is a decent bug/issue tracker and the main existing feature that I feel needs a revamp is the search. It just doesn't do a very good job, if you have used Basecamp I am sure you know where I am coming from on this one. Main problem is having to go into a project, then clicking the search link in order to start my search.
These issues have prompted me to build my own project management server/site. Being a PHP developer and having used Drupal a lot I think it will do the job, as it can take care of the basics such as users, types of content etc and allow me to focus on the workings of the rest of the service. I am currently weighing up the pros and cons between using a standard drupal install (probably D7) or Open Atrium (a Drupal 6 install profile that is basicly an intranet in a box).
So how can you help?
Email me the features you think that you want from a project management tool. Calender, mobile version etc
Send all ideas to project@creativecss.co.uk and I will make a follow up post detailing all the ideas that I recieved.
You can of course always follow me on twitter to get regular updates
