It will try to sync it as soon as it can. If you immediately close GitJournal, it won't be able to. Otherwise, on each modification it tries to sync. (Configurable) Maybe I can add some background sync.
The common use case to see and search through the notes works.
Is it good?
On mobile the common case is to launch an app and immediately see/search the notes.
Or type something, close the app and assume notes are synched.
But git pull and git push are not blazing fast operations. And there are no pushes, to get updates from the server immediately.
Git is a good storage, but I doubt it is suitable for notes without intermediate service handing note-specific scenarios.
