native widget used by QTabBar. It's easy to reach the number of open tabs
where the underlying system starts truncating text, replacing it with an
ellipsis. Adding a close button doesn't help of course; this affected the
tabbed document editor from KDevelop4, for instance.

set that mode (makes you wonder why KDevelop4 didn't benefit from that),
but the mode switch has disappeared from the current Kate code.

Hi, that's one of my hints from 2010
https://blogs.kde.org/2010/09/29/elegance-4-tab-bar-uncluttered :)

Definitely apps could be reviewed re the clutter even on Linux, KDE HIG can
help too. I am not sure if automatic solutions are possible for the KF
level.

neither Kate nor KDevelop, but is there an "official" or consensual opinion
about this (e.g. applications should call QTabBar::setDocumentMode
themselves when appropriate ... and can be patched if they don't)?
