ThreadNote 4+

ThreadNote is a simple text note application that stands out for its two unique features. Firstly, it eschews the traditional title list format; instead, all content, both titles and body text, is displayed in a list format (with a limit on the number of display lines). Secondly, it allows for the creation of child notes, enabling users to organize notes into a branching hierarchy of parent-child relationships. Users can navigate between parent and child notes with left and right swipes, and can use pinch in to fold notes down to just the title and the first few lines of text (configurable from 0 to 10 lines), with a pinch out gesture to unfold. This folding action can also be performed by tapping a button on the note.

Features:
- Notes with titles, body text, tags, creation and modification dates
- Note filtering through string and tag searches
- Note editing and deletion
- Tagging
- Bookmarking

Note Sharing:
- Notes can be exported to other apps or file folders via the action button on the note editing screen.
