The character tab/deck of the sidebar shows all sorts of information about your font: Family, size, bold Y/N, Italic Y/N and others. Many of these - specifically, the ones I mentioned - are actually defined separately for each language group: Western, RTL-CTL and CJK. But the tab/deck does not tell us _which_ language group it's currently showing controls for. This can be quite confusing when working on text with mixed language groups - and when the same font family may be used for multiple language groups. Of course, if LO only has one language group enabled (i.e. Asian/CJK scripts and RTL/CTL scripts are disabled via options) - then indicating the language group is not necessary. Now, as for _how_ to indicate the language group... that's not entirely obvious. Some possibilities: * If a control for the language is added, that might be a sufficient surrogate * If a control for switching language groups is added (see bug 153991), then hovering over it could tell us what it would do, in a tooltip, e.g. the tooltip could say "Western -> RTL", then when you click it, "RTL -> CJK", then again "CJK -> Western" - and you would know that the group on the starting side is the active one. * If a control for switching language groups is added (see bug 153991), and its big enough, it could say "CJK", "RTL" or "Wes". Or something more graphic instead.
