Two things that I would like to see: * horizontal (landscape) mode, especially the tablet / desktop (web) version, maybe with something like timelines mentioned here * some way of marking when beginning and end of box representing even actually falls on begin and end time (perhaps bolder lines, perhaps some shading, perhaps adding "handles" i.e. ------- to -----, etc.)

I also wonder how do you represent whole-day events.

Great work!
