Format - Bullets and Numbering - Customize tab Separator label should be bold. (issue not addressed explicitly in https://wiki.documentfoundation.org/Design/Guidelines/PropertyDialog)
Disagree with bold. "Separator" is an uncommon sub-level heading and captions the following "before" and "after". If you make it bold you better introduce a GtkFrame to also have Separator aligned with "Numbering". My take on the subject: before/after needs indentation to the caption. Looks bad, though. I wonder if we can do "Separator: before [ ] after [ ]".
(In reply to Heiko Tietze from comment #1) > introduce a GtkFrame to also have Separator aligned with "Numbering". Considered aligning Separator with Numbering, but -- in a way -- the Separator is part of Numbering. Moving Separator in line with Numbering seems to break up the connection/relation between Separator and Numbering. "Bold" was proposed to keep the relation, but highlight that it was not a control. > My take on the subject: before/after needs indentation to the caption. Agree (as per design guidelines) > Looks bad, though. Hence my proposal for a minimal change (i.e., bold). > I wonder if we can do "Separator: before [ ] after [ ]". Gives wrong (radio button) impression of either "before" or "after" -- when both can in fact be used. OP was meant only as a trivial cosmetic step. You are welcome to "hijack" this bug to become a more general redesign/refinement of the Customize dialog or close as WF.
My take here is that bold for non-headings give a false impression rather than radio-button-like arrangement. But let's keep the ticket open for a while waiting for others to comment.
