Here is my wishlist to save my wrists. I'm using MyGeneration for serious now and these issues are the most urgent for me.
1. Switch using ctrl-tab between simultaneously loaded templates (needs mouse clicks now, bad for RSI). Maybe we can use CTRL-SHFT-TAB to switch between template representation screens (Template Code, Interface Code, etc), although this is just a nice-to-have since I don't use these other representations much.
2. When a template gets the focus, make the edit screen get the focus (I now have to click on the text to set the focus which is not good for my RSI)
3. CRTL-F = FIND, F3 = FIND NEXT, CTRL-H = FIND/REPLACE. This would save me a lot of clicking as well.
