How to increase the amount of times one can use REDO option? Can the number of redos be increased? My limit is like 5 and I need at least 100 because I am new to this and mess up ALL THE TIME. I tried ... [EDIT] [PREFERENCES] [INPUT] but can't seem to find how to solve this. Anybody know?
Don't you mean by any chance UNDO steps?

They can be increased here:
Edit > Preferences > System > Undo steps



The maximum is 256, but that should be enough in most cases.
