I've moved all items in the hopper older than May 2023 to a new Hopper Archive (a sub-board of the Hopper). This is more of a clerical/organizational thing than actually removing items from the Hopper. Any item in the archive can still be revived by creating a new entry in the Hopper.
The archive also includes all previously Clarked bills for historical context as well. I will be doing the same thing with the CRL board in order to clean it up a bit.
