From bitter experience, I'd say "don't try to use gparted if you've
installed Raspbian from NOOBS". NOOBS seems to create all sorts of other
little partitions which prevent gparted from working. I installed and
configured my new Pi4 on the 16 GB card that it comes with. But I'm left
with only a gig or so of free SD space. I thought I'd be able to copy the
card onto a 32 GB card and then enlarge the almost-16 GB partition to use
all the remaining space... but those pesky little partitions seem to get in
the way.

Can I be arsed to start again from scratch, installing onto the 32 GB card
(but not via NOOBS!) and then doing all the configuration again? TVHeadend
is a real pig to configure, because it "sees" all the regional versions of
ITV1 as having the same name, whereas I want to call them "ITV1 London",
"ITV1 Yorkshire (West)" etc so I can watch/record whichever local news
happens to have greater coverage than the national news for a local story.
It's a case of going through looking at PIDs and matching them against a
list such as https://www.lyngsat.com/Astra-2E-2F-2G.html. Tedious, but I'd
got it set up just right - and then discovered the low free space and
thought how restricting it would be if I want to install anything extra.
