For my company we use 37Signals online project management software. Been using is for almost 6 months and really like it, the online collaboration ability of it is initiative and easy to use. One thing I am having a problem with it though is its not very visual. I like to use MindNode at times to break complex task or projects down. I thought I could use it to create a nice visual timeline but its not ideal. I really hate gantt charts and simple want to show the project time line, and milestones in a very attractive visual way. Also with the ability to easily change the dates (as this always happens). Thanks much!
