The beta version of Simplenote’s web client will export notes as text files and will use the note title as the name of the text file. When I’d previously exported from my Simplenote library the text files names were all GUIDs.
This is obviously much better. It means, as long as you don’t mine plaintext, you can get your data out of Simplenote in a portable and useable form.
To use the beta version of the Simplenote web client use the URL simplenote.com/new.
I’ve been using nvALT to enable data freedom for Simplenote , but it’s good to have a second option. (nvALT works on Mojave, but had issues with High Sierra. I’m planning to skip from Sierra to Mojave.)
PS. Recently Simplenote added plaintext note import, though needs Electron version for Mac.
 It took years longer than it should have, but Automattic fixed search in the Mac client.
