Organizing objects on the 4 (free version limit is 4 layers btw) layers, locking/unlocking (as well as hiding in fact, a hidden layer doesn't allow selecting) can help in dealing with loads of instances.
The free version needs limits, else users wouldn't buy licenses otherwise.
Whatever the limits are, there always be people to ask for them to be pushed/removed.
And well, you can go through all the regular contests to try and win C2 licenses.
At the beginning of this month, the rotary contest ended, the hbgames one started.
