I would like to request a simple addon that locks and unlocks camera zoom level at set distance, by tapping a single button.
Use case: I set camera distance that I like -> I click designated button -> buttons that zoom in and out don't do that anymore untill I click designated button again.

Problem that this addon would be solve:
Many people (including me) use middle mouse button to activate an ability. However in the heat of battle (pvp) we sometimes move mouse wheel a little while pressing middle button. That results in changing zoom distance.
