StarTrinity Organizer. Online GTD tool, tree notes and to-do list management system

The StarTrinity Organizer is an open source web-based notes and to-do list and task management system, storage of text and image notes in hierarchical format, a GTD tool. It is designed for technical people, especially for one-man-company software developers (ISVs, independent software vendors).
The software is developed and used by me to efficiently develop multiple software projects, organize my thoughts, make plans, do brainstorming. I have developed the Organizer for myself for bug tracking, project planning, brainstorming, book and diary writing, as CRM and CMS system.
