It would be great, if there were more documentation to get started with developing for the remarkable and perhaps a few shared libraries with commonly used functions, e.g. just to be able to display a given png. Even if it were just a command line program, it would enable many usages. It is trivial to compile Go programs for the reMarkable - just compile with ARM as a the target architecture. One can do that on any machine with Go installed. But for the lack of APIs, I have had no idea yet where to reasonably start with programming the reMarkable.
