All are my opinnions:
1. yes, because hitting home should be the first thing when you start programming new stage look (I can't immagine other use of this button). When you want to write a letter you pick up a blank paper. Home function now works as if you took a page with useless text and used rubber to clear it and write sth new.
2. 100% but untaged (in the future).
All those might be configurable from setup (eg. default brightness)
I don't know what others think, but IMO it would make programming faster.
That might be also a good solution
