I like using boxes to group things in a space. Sometimes I have a box of things that I want to keep around but I want to indicate that the box is no longer relevant. Maybe “archived” or something with some visual style to indicate that it’s lesser. I’ve tried making the box grey but it doesn’t communicate much because the background of the box is behind the cards.
(I don’t think an archived box needs to be read only, a visual indicator alone would be helpful, but if the contents of a box could be read only would be neat too (not strictly enforced, just to prevent accidental changes, e.g: someone could unarchive to edit a box)).
For now I just put a semi-transparent image over the box which is a dumb solution but it works (I drag the image out of the way when I need to interact with the contents of the box).
