Notes

Set Currency to Max:
Get out of combat, move where you are not near anything you can interact with, toggle on, then press ESC to open the menu where you can see your currency.  If you have at least 1 of the currency you will have the max amount.  Toggle back OFF to prevent option affecting anything else.

Experience:
Press ESC to see your Experience value fill in here.

Health:
For Player Stats, you typically have to set both the normal and the REAL values to the value you want for it to take hold.  Note also that level up or save/load may reset these values which are calculated from time to time based on your experience and level.
