Multiple Artboards Selection for deletion
Since we dont have the multiple artboard seletion for (Deletion,Editing),Every time user has to select on the single Artboard and have to do the changes, that consumes more time if the artboards are more.
In easier terms ,Its hard to select everytime the artboards and to move it...
In the latest versions it is possible to select multiple artboards, both on canvas an in the panel, using Shift and Ctrl/Cmd modifier keys.
If this still an issue for you, please comment back.
