An option to lock the arrangement of widgets on a dashboard, rather than having them floating into new locations when browser window is resized, would be very helpful.
I don't have a screen(s) to dedicate to a dashboard view, I resort to just keeping the dashboard on a tab. When I may need to resize my browser for some reason I can't count on the widgets I need to glance at quickly being at the top of page when I open tab showing my dashboard.
Additionally, when creating a shared dashboard, the intended arrangement of widgets isn't as expected when viewed by others based on their particular resolution, browser size, etc. This is frustrating and has discouraged me from to trying to use shared dashboards in certain circumstances even though they could be quite useful.
