Calendar in sidebar

I have been using eM Client for about 8 weeks now and think it is an amazing product. It syncs really well with Google unlike Outlook. There are only two things that Outlook does better (and one of those I see is supposed to be in the next release.

The other - In outlook I can show a calendar in the sidebar which I used all the time to quickly check dates. I could also change it to show more than one month which was sometimes useful as well. I really miss this feature. I do not use the features in the current sidebar. I would love to see this as an option in a new version.
