Feature/Fix request - Settings option to hide Complete/Delete dropdown for selected items on the new UI(as it's annoying for people already using hotkeys)

Found annoying new Complete/Delete dropdown for selected items for the new Workflowy UI as already know and use related hotkeys. Few more unpleasant results of this new UI feature are:

- attention picking almost each time it popups and as result disruption of thoughts what was intended to do

- it popups over text sometimes that lead to necessity to click somewhere else to read text under popup

Please allow to hide it using new settings option for example.
