Since I am a lone developer with no one to exchange ideas with I wish that you guys could fill in the gaps.

I am searching on the 'hot' or 'cool' features of applications of todays standards, and I would like specific ones like for instance adding a 'Search History', stuffs like that. Or perhaps you could point me to a downloadable application that is feature rich (aside from Outlook of course).

This will be in n-tier environment using C# 2005 and the project is for Property Management and Asset Register, it will also have a GIS feature.

Thank you so much guys!
