Here is a visually and functionally improved form for action.undo.
I got tired of having to scroll to the page bottom to find the RESTORE button,
so I added a RESTORE button to show for every diff block
(one can have multiple submit buttons in a form)
To make it more obvious that one still needs to click the little radio control
I added an arrow and used some color.
I also added a horizontal rule, to separate blocks visually better.
I left the table cells, but i am not sure why there should be any.
One very important thing I'd like to have added to the form:
A check that a radio button is clicked.
because right now if you do not select a radio button and click RESTORE,
the whole page gets scrapped without warning!
Here is the page source:
! Undo Changes
Select an earlier version of this page, to restore it.
<color=red>Warning: any current content on page **{p}** will be
overwritten.</color>
[(search group={p} dir=stamps template=unstamp order=reverse)]
/*

[form]
