Feature request: imported calendar filters + standalone forecast view

I have like 6 calendars. I want to see only two in omnifocus forecast view.
I would find also beneficial to have forecast view as a standalone “Calendar-style” icon on dock. the reason is I have many custom perspectives (different clients with multiple projects, one context and project List for each client).
Current workaround is to open in a new window the forecast but is not a real “standalone” one-click source of info. I would ask to create a simple applescript that launches the forecast view and opens in dock a link to this view with the symbol of the forecast view, mimicking a standalone app.
