[Feature] Notification badge options on mobile app

Use case or problem

There are two common reasons for using notification badges. (1) Incomplete tasks, such as in many popular todo list managers and (2) open files, such as in text editing programs, such as Drafts for iOS/MacOS.

Proposed solution

Enable options to do the following:

  • Display a notification badge for incomplete tasks. Can further specify tasks that are contained under a #todo header, such as in the Checklist plugin.
  • Display a notification badge for files within a specific directory. For example, some users may have an “Inbox” folder with notes that need to be organized and filed away.
  • General notifications for app changelogs, file conflict/merges
  • Display a “mini-badge” next to files in the file explorer
