If there are many text sections on one page, managing of sections can get a bit confusing, because every section in the panel (where you can manage the sections) is labelled as "Text". I think, it could be helpful, if either

if you click on a section to manage it, the section you clicked on would be highlighted in the panel

or

if the label would contain the first few letters/words of the the text of the section you clicked on instead of the word "Text"

or

if you could right click on a section and then change the options of this section.

Any ideas about this?

It's already there. Just doubleklick on a section's name in section manager to relabel it.

I agree that such a highlighting would be helpful.

Ah, shame on me that I didn't realize this. This is very helpful :-)

Here is a small plugin that highlights the sections in Section Manager when hovering content sections.

get HighlightSections 1.0

Installation:

Unpack the ZIP into your /addons directory and install it via
Admin Toolbox → Plugins → Manage → Available → Install

The highlighting is yet just a simple red outline - you can change this by editing the section-sorting-highlight class in HLS.css in the plugin's directory.

juergen, you're awesome and incredible fast. I'm once more pleasantly surprised about you. It's exactly what I was looking for. Thank you very much for your effort and all your help and support for typesetter almost every day.

In case you and everyone else reading this haven't yet discovered the color labels:

Clicking the bluish grey left border pops up a color label selection, which also improves the handling of more complex section structures, especially with many wrappers:

Never realized this (but I usually don't have to cope with complex section structures). This could come in handy, indeed. You never stop learning... Thanks again, juergen :-)

:) I did'n noticed that too.  Only my custom sections was labeled till now)

Use colors marks from time to time.
