Firstly, I’m excited to see sections in Impress!
Is there a way to move sections around?
Background: I have a large slide deck I use for my training programs, and depending on the audience, I include certain sections and move things around. One of the reasons I’m still stuck with PP 
No, I don’t think so.
The sections aren’t even visible in the Navigator.
and move things around.
I think the “Custom Slide Show” feature is well-suited for this purpose.
Go to the Slide Show > Custom Slide Show menu.
There, you can define multiple and different slide sequences.
The implementation of sections in LibreOffice is not yet mature.
I think they are still working on it.
This video from Colabora onLIne (fork of LibreOffice) seems explain the sections, but in LibreOffice there is no expand/compress section options in the slide panel.
With LibreOffice 26.8.0.3 I just noticed:
.uno commands available with regards to section

Version: 26.8.0.3 (X86_64)
Build ID: bce0998afefdbc355585ca324285661a2170ba77
CPU threads: 8; OS: Windows 11 X86_64 (build 26200);
UI render: Skia/Raster; VCL: win
Locale: en-US (it_IT); UI: en-US
Calc: threaded
It seems that there is something more than expected, but hidden.
Those commands should at least be in the slide panel popup menu.
In any case, I can’t find UNO commands to hide/display the sections as shown in the Colabora video.
Let’s hope they implement it soon.
Firstly, thank you all for responding; it was my first question here.
The Colabora interface looks a bit more like what I need. I recreated the toolbar, which sort of works, but I’m not sure if this is usable for me. I’ll dive into Marco’s to see if there are more options there.
Menu > Tools > Customize
This helps, but not for my use case.
The point is I have about 70 sections, and with PP I can drag them in the right order after a collapse all. Moving them around 1 section at a time makes it very labor-intensive.

the question is : when LO will be obsolete, as openoffice was years ago
