It's my idea for Tasky design - new to-do manager for elementaryOS. Considered and redesigned "NotNow" app from my gallery: [link]
EDIT - 2:
- "Disabled" searchbox in first window,
- Deleted Undo/Redo arrows, I don't think it's necessary here,
- Changed text in searchbox.
- Added first-run-screen
- Added icons in 128,64,48,32,24,22,16px
- Added icon preview in Plank with count tasks badge
