Just throwing out my ideas how it can be resolved, you don’t need to do any of them but throwing out possible sollutions.
a) Canvas gets bigger depending on the biggest (in animation) camera size? Like the canvas gets about 10% bigger for every +1.00 of the biggest camera size. It would cap at 20.00 or smth.
b) When in panning mode, you can increase/decrease the size of every stick at once. With an option to also include the camera in the scaling, as well as another checkmark to also have locked sticks affected as well.

b method also potentially could allow the possibility of having all sticks rotated with the knob from the canvas center but eh… That’s a bit of work and don’t wanna throw in too much of work- Unless it would just take 10 seconds to do, then maybe ;>->
