I’ve stumbled across Joplin, an open source / x-platform (and Free) note-taking / ToDo app. Thought I’d mention it since apparently we all need many many note-taking apps
Joplin is a free, open source note taking and to-do application, which can handle a large number of notes organised into notebooks. The notes are searchable, can be copied, tagged and modified either from the applications directly or from your own text editor. The notes are all in [Markdown format] (Joplin - an open source note taking and to-do application with synchronisation capabilities).
I’ve been playing around with it for a few weeks now, and it is very nice!
iCloud sync is not (officially) supported, but I’ve found using an icloud folder as source works on the mac, not on iOS. I set up a webdav for it on my raspberry pi vpn server, and that works very well.
