Ability to keep report preview windows, templates AND appointment book open simultaneously

Is it possible to have the ability to keep multiple windows open simultaneously? 

When editing a standard letter it is possible to keep this open and use the appointment book simultaneously.  Is it possible to extend this functionality to reports and templates?

Assuming the appointment book is always open, if we wish to run a report and preview it onscreen, it is necessary to close this report preview to be able to use the appointment book.

Similarly, if we are editing a template we need to close this in order to be able to use the appointment book.
