This does look awesome Stephen so forgive the selfish RTC request - I don't want to seem like I'm diminishing all the other incredibly amazing / mind blowing things you are already bringing. I don't know how I've gone this long without having a REX but I did and I've spent the last two weeks positively giddy with my new capabilities. I used to have different M100s for different projects and would grab the appropriate one when I wanted to do that thing. My (now horribly neglected) satellite tracking project for example. Because of the size of the Keplerian database and my lack of ambition to do anything like load stuff from SD card I just kept it all loaded on one unit. Now I can pop that image on the current M100 I'm working on, copy it to my phone, sync via dropbox or GoogleDrive and play with that image on VirtualT then reverse the process to get it back on physical hardware. It's downright amazing. Everyone needs a REX.
The RTC request is based on the way I utilize my M100s. I'm constantly doing a total wipe on them for one reason or another but I use Idea! pretty heavily and rely on a correct date/time. Just always thought it would be nice if it was always correct since it's something I constantly forget to set.
