Not yet had time to consider to learn another new system.
Been too busy improving PicoMite for PicoCalc.
At the moment a short break to recover, then I will decide, in the meanwhile the source is available.
I highly recommend taking the time to learn git – it really is useful to know, to say the very least, especially since you will then be able to take advantage of distributed version control and host your code on a git forge such as Codeberg, GitHub, or GitLab.
