@telumire thanks for sharing, some key features I like in your approach;
- Drag and drop or toggle status
- Create in context ie todo button
- I imagina create doing or create done would have its uses
- Create then set tiddler type on demand
- Manual reorder
Once nice thing about Projectify is to drag and drop on a project to “change” project.
One thing my solutions also include is the ability to flag completed todo items as a reference or archive items, when it contains information to retain. Otherwise done todos can be “purged” occasionally.
I like your example @telumire because it is making greater use of tiddlywiki features to have intuitive, functional yet a minimalist UI.
