Please add a modifier key (Shift is standard) to constrain dragging to vertical, horizontal and 45 degree.
I used VS several years ago and requested this feature. Is there now a way to move the camera at a constrained angle?
We have 4 control buttons on the bottom left of canvas and you can use these to move the canvas through vertical and horizontal.
If you have an image (or multiple images) selected you can also use the up/down/right/left arrows on the keyboard to move it/them through vertical and horizontal.
45/135/225/315 are not specifically covered at the moment buy one up, one across will effectively achieve this if a little painstakingly!
