Sometimes, like when you're leveling up, its better to work on your character sheet outside of game time. Rather than having to the game, which may trigger your audio or video, every time you want to work on your character sheet, it would be easier to work on it elsewhere. I suggest a space, maybe within the Character Vault, where you can choose "Active Characters". There you would select a Character/Game combo (e.g. Darak in the "Multiverse of Shadows," as opposed to Darak in the "Dark Princess One Shot"). You can then edit that character sheet right there. Any changes you make to your character there, you would see in the game. This could also allow the designers to use more of the screen real estate for the sheet, making it easier to do things like enter spell details, especially if you're on a small laptop or tablet screen.
