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 (exporting) - Changing the order of notes - Moving notes between parents and children Note Sharing: - Notes can be exported to other apps or file folders via the action button on the note editing screen. - Options to select only the note being edited, all its siblings (notes at the same level), or all its descendants (notes at lower levels) - Select multiple output items: title/tags/creation date/modification date/body text - Auto-numbering: Automatically numbers titles when exporting multiple notes (optional) Settings: - Changing the font of titles and body text in the list and editing screens - Changing the base color - Dark mode toggle - Adjusting the maximum note width - Setting the number of lines for folded display in the list view (0 to 10 lines) - Setting the maximum number of display lines for body text in the list view (up to 500 lines) Other: - Backup and restoration of all data Limitations: - Only handles text. It cannot manage images, audio, location data, etc.

1ヶ月間の予定を時間まで、1画面で確認できるカレンダーです! ●これに当てはまる方におすすめです!! ・バイトの予定を管理するために紙の手帳を買って、マンスリーのページのみ使っていた ・予定の詳細を表示したり、スクロールしたりせず、1ヶ月間の予定の時間まで1画面で確認したい ●このアプリは学生時代のバイトを思い出して作りました。 バイトのシフトを管理するために、1cmくらいの厚さの紙の手帳を買っていました。しかし、使っているページはマンスリーのページのみでした。予定の書き方はバイトの「バ」に19:00~22:30の勤務で、「バ19-22:30」などと書いていました。友達も同じように書いていたので、1ヶ月の予定を時間まで1画面で確認できるものがあれば嬉しいのでは考え、このアプリを作りました。 共感してくださる方、興味のある方は使ってみてください! 今後として、現状が最小限の機能のため、良いアイデアがあれば追加していきたいです。
