Does Settings save when I change something?
Yes. Settings keeps each change as you make it. Only the Storage details wait for you to press Save.
You don't need to press anything. Settings saves each change as you make it, and says nothing about it. Close the window and open it again, and every change is there.
How fast it saves#
A switch or a choice is saved at once.
A box you type in, like the file name, and a slider, like the JPEG quality, are saved a moment after you stop, or when you click away.
The one thing that waits: Storage#
The details for where share links upload to are different, because a wrong password or bucket name would stop uploads from working. When you change one, a bar slides up at the bottom with Unsaved changes, Revert and Save.
Save keeps the details. It says "Saving", then "Saved", and the bar slides away.
Revert puts the Storage details back the way they were.
If you close Settings with Storage details you haven't saved, a sheet asks Save your storage details? and says "Everything else is already saved. These details are saved once you press Save." Choose Cancel to stay, Don't save to leave them out, or Save.
To set up storage, see choosing where uploads go.
