Otherwise, a great start -- I absolutely love that a little map shows up for the next appointment, wanted this for years.
Feel free to email us any feedback, our goal's to make this as awesome as possible, not to screw with your calendar!
My UX suggestion is tread carefully when you're within someone's pre-existing content, doubly-carefully when it's email, calendaring, and docs that may involve their colleagues and clients.
I'm on Chrome + Ubuntu 12 in case that's useful for your debugging.
Your main value prop is: Know what you have to do in the next 48-hours. But the problem is, I have to go open up my calendar to see that with your app...why even install then, when GCal can tell me what I have up in the next 48h.
The key would be for it to run in where I spend most of my day -- my inbox, not my calendar.
Agree though to the 48-hour limitation -- would be great to one-click side load appointment information for any day of the week, not just the next two days.
Don't know if it has wide appeal, but I would love that.
Time to start using descriptive terms in headlines, not obscure names.
