How to save and persist edits in v0 design mode

From the official Vercel PR announcement here:

it states “make quick changes to your UI without editing code or spending any credits”.

So I, again, am wondering if I am missing the way to APPLY/SAVE/COMMIT those visual edits. Yes, it’s much quicker to change font-size etc.. with a familiar GUI/toolbar but if I have to unnecessarily click ‘Apply’, wait for the processing, and spend tokens, not sure I’m seeing the value.
