Something that would be nice for the Pathfinder 2e character builder is if you have a level up waiting to have a button that will take you to the level up screen. I could not find one, though I could be completely blind. (Which is always a possibility) I had to take a longer way to get to a level up, which my players would be discouraged if they had to do that and try different means to build a character.
Good news! If you click on your character’s avatar in the top left corner of the sheet, it pops out a sidebar where you can navigate to the builder. Eventually, we may add an additional way to navigate there, but it is possible from the sheet right now by clicking on your character’s avatar and then clicking “Character Builder” when it pops up on the righthand side.
