[Feature request] Make file tabs available in multiple rows

[spacemanspiff2007]

When there are more files open than the screen width a very tiny scrollbar appears which is very hard and annoying to use.

It would be nice if there is e.g. a config option to show the tabs in multiple rows. Imho it would even make sense to make this a default so the user has to actively deselect it.

Tabs are handled by Qt. And multiple rows are not implemented there. Might be possible to do something non-standard.

It would be already a huge improvement if the scrollbar is not on the right side and very tiny. Instead it could be below the tabs and span over the whole width. That way scrolling would actually be possible. Maybe that way the standard control could still be used. E.g. maybe set setUsesScrollButtons to false
