To your credit, the feature you're adding is far more important to me than any of the minor Evernote features the parent mentions. So don't sell yourself short.
I currently find myself stuck syncing text files using SyncThing or ownCloud or making notes in my KeePass database just to get the level of privacy I want in this.
I saw Turtl before and this makes Turtl highly appealing to me, I'll definitely be trying it out more thoroughly as it looks like mobile support has matured since last I tried it.
One thing I seem to remember having an issue with was DPI scaling support, I use 4k screens at home and at work, but everything was blurry as the apps didn't support DPI scaling - any chance this has been addressed?
Another issue I seem to remember was self-hosting, I'd most likely self-host it (though I'll definitely chip you a donation if it's all working), but I didn't see any way to configure the server used - did I miss something or has this been added now or would I need to recompile to do this?
Thanks for all your hard work.
EDIT: Just tried it again - DPI scaling on Windows is now working and there appears to be a button to change the server. Sweet. I'll be moving in to this tonight if all goes well. Thank you again. This looks like an excellent product.
I noticed your page doesn't have a donation link though and since I intend to self-host I can't send you anything, any chance you can put one up?
EDIT2:
Hmm, noticing something strange here - I thought the DPI scaling was working when I saw the notes in the main screen looked very sharp, http://i.imgur.com/BfSDcca.png but when I view notes expanded it seems to lose its sharpness. See http://i.imgur.com/gpJ7zsC.png
I'm not sure what the reason for this is but I've noticed similar problems with Atom and other browser based solutions so perhaps this is unavoidable for now, in any case it's much better than it was before.
