Two Team Explorers in TEE 11 Beta – twice as good?
When you install TEE11 Beta in Eclipse you will notice their are two Team Explorer windows
- Team Explorer 2010 – The old style window
- Team Explorer – The new VS11 style window

This is an artefact of the beta as TEE transitions to the new VS UI.
I would recommend you use the new one as this will be the experience going forward. I certainly would not recommend having both open as I have shown in this screenshot
