Titanium has a great and very active community. The QA forum is a great place to learn.
The other day I came across how to turn off the Titanium Studio dashboard.
I find the dashboard useful as far as seeing what is new from Appcelerator, but I know many want to remove it due to startup times.
Here is the QA posting: http://developer.appcelerator.com/question/125251/dashboard
The details:
On OS X simply open /Applications/Titanium Studio/TitaniumStudio.app/Contents/MacOS/TitaniumStudio.ini
and add -Dtitanium.hideDashboard=true to the last line in the file.
