What to put on board besides pedals

Picked up a new board last week along with a quad cortex and volume/expression pedal, however I miscalculated the dimensions I would need and wound up with way more real estate than necessary 🤣 the best solution would obviously be to get a pedalboard that actually fits my rig but I like having the extra room in case I want to expand my setup down the road. Only problem is now I'm using like maybe 40% of my board space and it feels so naked, anyone have any suggestions on space-taker-uppers?
