Traditional version control system are displaying versioning information by grouping Projects->Folders->Files with Tree view on the left and details view on the right, then you will click on each item to look at revision history for that configuration history.

Assuming that I have all the historical versioning information available for a project from Object-oriented model perspective (e.g. classes -> methods -> parameters and etc), what do you think will be the most effective way to present such information in UI so that you can easily navigate and access the snapshot view of the project and also the historical versioning information? Put yourself in the position that you are using a tool like this everyday in your job like you are currently using SVN, SS, Perforce or any VCS system, what will contribute to the usability, productivity and effectiveness of the tool.

I personally find the classical way for display folders and files like above are very restrictive and less effective for displaying deep nested logical models. Assuming that this is a greenfield project and not restricted by specific technology, how do you think I should best approach this?

I am looking for idea and input here to add values to my research project. Feel free to make any suggestions that you think is valuable. Thanks again for anyone that shares their thoughts.
