Despite the colorful image in the ads, typical CalSync users would have a single color in their calendar events, as color is per calendar, which makes It a bit less interesting.
I am an Outlook Calendar user, and use 7 or 8 categories which help me organizing though coloring each event in terms of its category (blue lessons, red research meetings, etc).
I was wondering if It could be possible for the app to give the users the choice between using a per-calendar color and inheriting the color of each event from its own color (category) in the original calendar? I think It could make the planner much more useful.
