5E - LVL UP button

First off, I have to say thank you for the LVL UP button even though until just recently I never knew it was there.

Question about the multi-class function when using the LVL UP button; should it be checking the characters statistics to validate that the character is eligible for some of the class? Like if you are a fighter with a 8 Intelligence; then they are not eligible to be a Wizard.

I don't think FG does that kind of background checking.
