If resizing the trainer is a bit unrealistic, I actually liked the version of the trainer you had where you had everyone's max/inf.hp and 99 skill use as just two codes. The only problem was already mentioned, that being the hotkeys interfering with other in-game controls.
Could you please repost that trainer with the hotkeys removed?
Sorry I had completely forgotten about the "small" version of the trainer I promised to make. So I have created one now but just so you know it isn't the most beautiful thing out there
