Boardo App concept

Hey guys, I need some feedback.
Some time ago I was working on the concept of simple old fashion iPad planner. Idea was to make simple and stylish To-Do app which people could use as To-Do stand on their desktop.
You can scroll lists with swipes or choose one in scrolling list, you can drag tasks between lists and (main feature) you can erase task by your finger like on real chalkboard.
Should I continue work on this app? Would you like to use it? What should I add or change?
