There are a number of (small) requests for specific items in flyout menus — I’d like to consolidate that, here, into a GENERAL request in the hopes that it will get a larger response. You may not care if Cmd-J (Ctr-J for PC folks) will duplicate a layer as in Photoshop, but maybe you want to be able to create a new swatch with the key press of your choice.
