I've been doing that for quite some time as well, but recentlish (<6 month ago) stumbled upon BoostNote [0] (electron based) and have to say that I think its pretty neat.

Especially because I can (if it ever becomes unmaintained), export the data to my preferred format with a simple script, as everytthing is saved in plain json files.
