Hi,
Since Dashboard as it stands is a compilation of different views, why not bring it under the Views sidebar?
Add a Dashboards section below Recent which will list all the Dashboards.
Then allow a Dashboard to open in a new tab / workspace. That way I can have a/the dashboard open and available / ready when I open MLO.
Currently I've to go to View > Manage Dashboards to see all the dashboards and open one. I've a hotkey (F10) assigned to one but that is not a clean option since you need separate hotkeys for each dashboard.
And the dashboard opens in a new window which makes it pretty much the same as F3>open tab in new window but of course with extra views.
