It is still confusing to me the use of the word/concept “theme” inside XWiki.
Whereas, when I enter Administer Wiki from the hamburger menu I clearly reach Themes entry under Look & Feel, it is weird to me to find Skin as a customization alternative under Themes, and variables to set logo, typography or height of the navigation bar under Color Theme.
I would say that I feel more “natural” to find Skin under Look & Feel, at the same level as Themes, to rename Color Theme as Color and Icon Theme as Icon, to create a new “category” Typography under Themes to hold typography -related variables, Logo also under Themes.
LESS code, as advanced option, also directly under Look & Feel!
What it is no clear to me is where to put the height of the navigation bar and the breadcrumb separator…
Just my two cents! Thanks for the hard work!
