In Writer, we have several kinds of supported named styles: Paragraph, Character, List, Page Sequence, Section and Frame. (There is also Table pseudo-styles, but see bug 152711.) When we open the sidebar and choose the styles deck, the upper row of icons offer a selection of style category. But - Section styles are missing. They should be there. (Of course, it should be possible to actually edit named Section styles, and that's filed as bug 170409.)
If bug 170409 will be implemented, what I disagree, the style should be accessible in the Stylist, of course. No need for UX input. I don't think we need a ticket for this now. It's part of the section-style implementation, or could be requested as follow-up if not done. => INVALID
(I claim that) Styles of _all_ categories _must_ be accessible via the style pane of the sidebar. And that is why I marked this a bug, not an enhancement. This principle is important for several reasons: 1. It constitutes a uniform avenue for defining and editing styles, while on the menus, toolbars, notebookbar etc - the handling of styles of different categories is scattered across different widgets and locations. "Edit it from the sidebar" is easy to remember. 2. The presence of the different style categories is of _educational_ value to users: It introduces newbies, or users who are unfamiliar with certain style categories, to these categories, like schoolchildren seeing the letters of the alphabet, or a collection of animals or plants or planets, in sequence of posters on their class walls. They start out not recognizing some of them, and gradually have the opportunity to notice and scrutinize them. And in the case of style categories - experience what happens when they are applied and edited. 3. The presence of all named categories in the style pane allows for the dynamic indication of the current named style of each category, for the content at the cursor or of the selection. 4. With the more frugal UI modes, almost all functionality needs to be accessible/executable via the sidebar.
