Having the option to eliminate CWs from the shop search would be very helpful. While searching for 'crown' after ~50 searches, I managed to get only ~3 searches returned that weren't CW items. I like CWs, they are pretty and the amount of effort people put into them is admirable! And I get that they need them to sell, but sometimes I just want cheap items to fill treasures.

Just a simple checkbox to include/not include CW items from the shop search would be very helpful.

If you're looking for items for your wishlist or pet TCs, you might want to use the item directory instead of the shop search. The item directory doesn't show CWs and you can search for things like 'crown', 'red' or 'flower' and get every official subeta item with those words in it.
