Hey I would like to propose a new feature when dealing with canvas interface mouse I/O events: IMHO, it would be a lot better if we had the possibility to drag/create a selection box when selecting multiple nifi components, instead of just having the possibility to shift-click to do multiple components select.
I would propose the following mouse key mappings: Right click -> Context-Menu (same as today) Right drag -> Move canvas (currently on left drag) Left click -> Select component (same as today) Left drag -> [New feature] Selection box Scroll drag-> Move canvas Best, Jøran
