Some tags/different colours would be cool. Also there's a bit of a mouse bug if you click on one column, drag, then reclick on another in the same sort of motion (you get two columns/days drawing at the same time).

Would be useful to have some borders or something too (I had no idea where to click or what I was dragging first go).

Nevertheless, conceptually it's sound.

I agree with the tags/colors suggestion.

For example, I am in the office all week, except tuesdays, when I'm available by conference call.
