Let's say there is a question in your saves, and you want to change which saves list it is in. As far as I can tell, the only way to do that is to go to the Saves tab on your profile (https://math.stackexchange.com/users/saves/177399 for me), scroll down until you find that question, click on the three-dots menu, and select the "Move to..." option. However, I have over 300 items in my saves list, so it is huge pain to find the one I am looking for. There is no way to search in the saves list. When you use the main search bar, the results do not come with a "Move to.." option.
The feature I am requesting is that you should be able to go to the question page itself, and change the save list it is in from there. Right now, you can only toggle whether or not a question is saved at all from the question page, by clicking on the ribbon icon.
One workaround is that you can go to the question page, click the ribbon twice to unsave and resave it. Now, the when you sort your saves in "Added" order, the question will be at the very top. I do not like this alternative, because it is unintuitive, and it forces you to change the order your questions were added in just to change a folder.
