I use half height walls and find that they greatly increase the playability of rpgs actually at the table. It’s really cool that Printable Scenery offers the rotating secret doors that are virtually indistinguishable from the normal sized walls. However, as a half-height gamer, I’m sort of stuck. If I put a full sized wall portion (that is a secret door waiting to be found), it sticks out like a sore thumb. Having a similar, half-sized rotating secret door in the standard half height walls would be a great addition to your collection.
