@vito I'll check this one out, thanks! I've been using #Joplin for couple of years, and I'm loving it so far! There's a sync source you just set (can be anywhere, local or remote, incl. #webdab, #s3 bucket, #dropbox or their own server where you can also selfhost). It's cross platform and you can take notes as markdown format.
