Hi, you're right - at the moment, you can only add Gmail accounts. This is a great suggestion though and I'll try to get to it in due course. I'm sure you understand this is a big feature, so it will take some time.
Sorry, but ICS is not supported any longer. You need at least Jelly Bean to use it.
This has been implemented now - finally :)
Fixed in latest update.
Fixed. Shows all starred.
You will need Jelly Bean or later.
