Write some paragraphs. Mark one of it and create a section (Insert > Section). Set cursor into the section and call Format > Sections. Click on button "Options". The vertical tab bar of that dialog has an item "Indents". This icon is "paraspaceincrease". It is not suitable because it shows vertical arrows whereas the section indent settings make horizontal changes. I have looked through the cmd/32 folder of the Colibre icon-theme. I have not found an icon that fits exactly to this section property. Best one of the existing icons is "incrementindent", because the default is an indent of 0cm and someone that uses this property will do it because he wants to increase the indent. Actually the "Indents" tab does allow to change indent before and indent after. So an icon should show two arrows, I think. But it is a task for the designer community to create a suitable icon.
Created attachment 202548 [details] Screenshot It adds space before/after like for paragraphs. No wrong, AFAICS. incrementindent.png is some arrow pointing rightwards, could be understood as tab, anchor, vertical indent. Not sure this would be more suitable.

The operation connected with icon "paraspaceincrease" for paragraphs increases the distance between paragraphs. That is a vertical operation. But the operation "Indents" of a section is a horizontal operation. In this operation you change the left and right margin of a section. Therefore I think icon "paraspaceincrease" is not suitable. A better icon needs to be newly designed.
Right! But then we have to change the icon for all indentation action; it is the same for paragraph properties, for example.

The horizontal indentation of paragraphs already has a different icon than the vertical spacing. Horizontal is "incrementindent" and "decrementindent". Which other indentation do you have in mind? The attached zip-file contains screenshots and examples that hopefully show, why I think, that "paraspaceincrease" icon is not suitable for section indent. Or perhaps the other way round, why do you think it is suitable?
(In reply to Heiko Tietze from comment #3) > Which other indentation do you have in mind? Thought about Paragraph properties. But in fact this variant of "indents"-only is only applied at sections. And PS/PDF has both horizontal indentation and vertical spacing. Code pointer: In include/vcl/tabs.hrc for the item RID_TAB_INDENTSONLY the value paraspaceincrease.png needs to be changed for incrementindent.png
