I love the OenRCT2 project so far and I enjoy the many added features.
I'd love to see a few more cheat options added.
Here are my few suggestions for cheats:
Disable Car/Train limit, example on a ride that only allows 6 cars per train you could force it to be 8 or more.
Allow an option to save cheats, for instance I always play with Freeze Climate, Show vehicles from other track types, and Show all operating modes, switched on. It would be lovely to have them activated always.
