Rune,
Seems at least a few members are requesting the capability of taking and saving a screenshot be added to NanoVNA-Saver. The python code is included in edy555's nanovna.py script. From my experience, the primary "got you" is the NanoVNA needs to be reset when taking screenshots of the version screen or a screen including the on-screen keyboard.
You might pow-pow with QRP regarding the latter two problems as he seems to have figured it out in NanoVNA Sharp V3. Not sure if he solved it by firmware modification or in code.
