A great app allowing quick and easy list tracking available from the menu bar. The developer is quick to respond and helpful. I experienced a problem after upgrading to Mavericks and he worked quickly to resolve it. While I like the simplicity of the app and wouldn't want to lose that, there are a few more features that would be nice - drag & drop for file attachments, image display support on an item, etc.
Great little Task-/Todo-/Project-Management App!
Always available via menulette and fully controllable via hotkeys/keyboard shortcuts.
The developer is very friendly and active and replies to any questions and feature requests.
