Open Source Gambas Note-Taking Apps

Markdown Tree Notes is a modern desktop application designed to help users organize, write, and manage their knowledge through a hierarchical tree of notes. Users can create unlimited notebooks, and nested notes within an intuitive tree view, making it easy to organize projects, documentation, research, personal journals, or technical knowledge. Each note supports Markdown with two synchronized viewing modes: Plain Text Editor – A distraction-free Markdown editor for fast and efficient writing. HTML Preview – A live-rendered preview that displays the formatted document exactly as it will appear, including headings, tables, code blocks, lists, links, images, and other Markdown elements.
