View multiple calendars on one screen

It would be helpful to be able to view multiple calendar filter views on one screen, potentially like the dashboard widgets where you can set a preferred layout. 

For example at the moment we are often flipping between overall month views, weekly trainer and weekly room views. I would be good to be able to have two visible at one time and ideally be able to save the layout as a default. It would also make it quicker when refreshing to see changes in the calendar. 

The below is just a screenshot example of two separate webpages which take up half of a screen each. We also often view the different calendar filters on multiple screens but it does make it more difficult to see them in unison and also every time a change if made and the page needs to be refreshed, they both automatically go back to the default saved view.
