Nice!
Though if they were double sided, there is no way we can see all these cards in the same shot. If it starts at odd numbers (i.e. #1), #3 and #4 would share the same card front and back, if it starts even (i.e. a cover graphic and #1 on the same card), #4 and #5 should share the same card front and back.
Alternatively when creating the ventoy installation you can chose to leave X amount of space behind the ventoy partition and then create your own data partition there afterwards. You lose the advantage of “dynamically” sharing the available space between ventoy and your data, but with the seperqte partition you can use whatever filesystem you like for your data, and there is a clear seperation between ventoy and your other data.
Right, didn’t think of that :)
