> The issue we're having is that we have a UI that uses a tab widget for displaying file contents - one tab per open file. Once a user opens enough files/tabs, the tab scroll buttons pop up (so far so good), but then the user keeps opening more tabs. Eventually they have enough open that it can take quite a while to navigate between open tabs since each click on a scroll button only shifts the visible tabs over by one tab per click. For example, if they have 10 tabs open, and because of screen size, tab elide mode, etc., they can only see 3 tabs at a time, if they are currently looking at the 10th tab, but want to then go view the 1st, they have to click 7 times to get over to the first tab.

But I don't see anything on https://doc.qt.io/qt-5/qtabwidget.html that talks about those scroll buttons beyond just the usesScrollButtons property. So I'm not sure how to specifically trigger off from a right click on the scroll arrows themselves...

What will that pop-up menu look like if there are 100 tabs open.
