Joplin is the best notepad I see. I think that because is some app to Windows, iOS, Android and Mac, and is synchronization by WebDAV. Now all my notes are keep in my private server and this is the best. But I need spell check. I see issue https://github.com/laurent22/joplin/issues/275 but is blocking by https://github.com/laurent22/joplin/issues/1128 and 1128 is closed Spell checking is abandon or in development?
