On the 5E OGL sheet when a spell is selected that can be cast at higher levels the option is given to select the level to cast it at, up to level 9. I would like to see it only give the option to cast at levels that there are spell slots available to the character. Example: A 3rd level character that has one 2nd level spell slot left wants to cast a Charm Person spell at a higher level. Currently the query box allows them to cast it at up to level 9. I would like t see it only offer up to level 2 as per the PHB.
