No idea if there's a suggestions category honestly so I'm just assuming this is the closest category to one.
It would be really helpful if, after reaching the max amount of pages allowed in a tab of the top navigation (7, I believe), a scroll bar was added to that tab so you could scroll down to see more pages in it. Currently, if you go above the limit of 7 pages, the extra pages added just don't appear, which is a bit of a problem in my case:
I'm an editor for a wiki for a game (The Tower Unite wiki, specifically) that's split into 3 main parts, one of which (Game Worlds) is a set of 10 games complex enough to have their own sets of pages for their features and maps. So, as the amount of games (10) goes over the limit for pages in a top navigation tab (7), I can't really represent them all equally: I wanted to have each game have a sub-tab showing its features and maps, but because of the limit, I have to set aside one of the pages in the tab to just being a "More" sub-tab so I can even show the remaining 4 games at all.
It would be a big help if a scroll bar was added so I could show each of these games equally in the top navigation without having the top navigation itself become any larger than it already is. I'm not sure if this is anything worth adding, since it'd likely only be useful for my wiki and maybe a handful of others, but I'd still really appreciate if it was added nonetheless.
