<p>Hi All, <br>
</p>
<p>Does someone know in JOSM if it's possible to select more than
one building, lets say a group of buildings and square them at the
same time?</p>

there's a JOSM warning called "crossing buildings". Again this

case where a neighbouring building is drawn over the top of
the other, even ever so slightly. (Often we see buildings up
against each other in the imagery. To be purely strictly
correct, these should be mapped as ways sharing nodes, but
it's understandable that folks don't always get that quite
right, and it doesn't actually matter that much). I sometimes
spend ages fixing all the "crossing buildings" warnings,

I've just been trying this script by first fixing the 100%
duplicates using the normal JOSM validator error, then next
selecting these cases using the script. It works! But it's a
bit fiddly to set-up and use. I was imaging this kind of
logic, but as a refinement to the JOSM validator itself. Under
the "crossing buildings" warning list it could show the
major/minor types of crossing buildings.</div>
