There is a cool collaboration happening right now between WTP and DTP to build a shared Servers view that will replace the separate WTP's Servers view and DTP's Data Source Explorer view. The new view is built using the Common Navigator framework and will make it easy for other Eclipse Projects to contribute content. One of the important goals is to reduce clutter on user's workbench by collapsing many individual views into one. If you are interested in this effort, you should check out Bug 252239. There has also been some relevant discussion on Bug 245013 and Bug 247934.
So, I am looking at you... CVS Tooling, Subversive, DSDP Target Management, SOA Tools, etc. You know who you are. Come join the party.
