Looks like a snappy note app
Website https://www.get-notes.com/ and https://github.com/nuttyartist/notes - https://github.com/nuttyartist/notes/releases
Although there is a release called "portable" I don't think it works yet as the database is still stored in %appdata% BUT it seems something that is on the developers radar Issue #545 Portable version that saves the database and settings inside the executable folder
A simple batch file to move the database/ini from/to is simple enough to make of course.
Features Overview
- Folders and tags. Organize your ideas hierarchically using nested folders and universally using tags.
- Markdown Support. Format text without lifting your hands from the keyboard.
- Different themes. Switch between Light, Dark, and Sepia.
- Feed View. Select multiple notes to see them all one after another in the editor.
- Always runs in the background. Use the hotkey Win+Shift+N to summon Notes. Ctrl+N for macOS.
- Keyboard shortcuts. Meant to have the option to be used solely with a keyboard (but more work needs to be done there).
- Native app (written in C++ with Qt).
- Fast with a low memory footprint.
- Fully open source and cross-platform (Linux, macOS, Windows).
- Completely private - tracks nothing.
