Hi, please take a look at the discussion thread about the new app Cross-platform app - development thread
Tutorial on first run is already there, same for the chat tab being the first in sight after launch.
The online guide is reachable via settings and opens a web view. In a few months time it will become a proper text page but in the meanwhile due to the sudden changes to the documentation I’ll leave it as a web page.
There is a configurable battery alarm with threshold. Current battery level can be seen on the LCD, I preferred not to duplicate info.
