Subject: Possible to change the order of my workspace tabs?
Nope. Can’t do it drag-and-drop style. But you can go ahead and build the list of tabs/sheets in the order you want, out to the right of the ones you have, then drag entire groups from the current tabs into those.
I would recommend first creating the new sheets, and naming them 1,2,3,4,5,etc. to keep them narrow, then after you get the database icons moved to them, delete the original sheets, and rename the new ones.
