So, does anyone know of a way to efficiently cut features in
multiple
<br>
layers using a polygon, and then to be able to select the pieces
<br>
(multiple layers) that are either inside or outside the polygon,
and
<br>
then delete them?

Disregarding the "multiple":
<br>
<br>
"Vector -> Geoprocessing -> Clip" deletes the items outside
the polygon
<br>

Nope, doesn't. - In my first point I said: <b><i>Vector Geometry
Processing Clip, but it wants to extract the data inside the
polygon and create a new file with the extracted data. (To be
expected)<br>
</i></b>but meant: <b><i>Vector-> GeoProcessingTools->
Clip, but..... </i></b>(my bad, apologies)<b><i><br>
</i></b>It does not delete, it clips them out into a new layer<i>
- which is not what I'm hoping to achieve.</i><b><i><br>
</i></b><br>
Thanks for the thought anyway, though.<br>

You would have to do it for every layer you want to be cut, the
dialogue box will stay open after cutting. If the polygon layer
contains just one polygon, no selecting is necessary.
<br>
<br>
BTW: make sure all layers share the same CRS (i.e. turn
on-the-fly-reprojection off)
