<p>Thanks Chris, Richard and Paulo for sharing your views. <br>
</p>
<p>I note that in 3.40.5, choosing 'Duplicate layer' does cause a
pop-up notice to say:</p>
<p>Layer duplication complete: Note that it's using the same data
source.</p>
<p>Although this does disappear after ~5 seconds.</p>
<p>I tried 'copy layer' and was baffled for a moment, then I
realised there was a 'paste layer' option which I had to do
(before anything visible happened. Yes, the layer definition was
copied to the clipboard when I clicked copy). <br>
</p>
<p>Both Duplicate layer and Copy-Paste layer work on multiple layers
at once, and groups as well. <br>
</p>
<p>Interestingly keyboard shortcut Ctrl-C Ctrl-V doesn't copy and
paste as you might expect. <br>
</p>
<p>Ctrl-C does nothing as far as I can tell. Ctrl-V gives me this
message:</p>
<p><span style=" font-weight:600;">Layer not editable: </span>The
current layer is not editable. Choose 'Start editing' in the
digitizing toolbar.</p>
<p>So I think it would make sense to remove the 'Copy Layer' /
'Paste Layer' options. <br>
</p>
<p>Thanks!<br>
Nick.<br>

People,<br>
<br>
A user had an issue in which she 'copied' a layer, edited
it and then found out she edited the original data...<br>
<br>
My response was: yes (join the club ;-)) it is called
'duplicate', but it only duplicates the layer, NOT the
data.<br>
<br>
Then she responded: but I did not use 'duplicate', I used
'copy layer' ...<br>
<br>
Then I found out they indeed both exist in the context
menu, and actually do the same thing... ???<br>
(tested with a gpkg and a shapefile)<br>
<br>
So my questions:<br>
- should there be 2 context menu items for the same thing
(the always tricky 'duplicate' which (in my view)
counter-intuitive does not duplicate data)<br>
- should these 2 functions not behave different?<br>
<br>
