Don't close the window when adding new widgets

[pixelknit]

Suggested new feature or improvement

Pinning widgets to the dashboard is great, however It's really annoying that the window closes when you add a new pin, so if you want to add more you have to open the pop up window every time, it will be great to have it there as you pin all the widgets that you want.

Scenario

Adding or removing useful system metrics, etc on the fly per project
