Created attachment 127293 [details] ideas If Okular is configured to open new documents in tabs, the tab bar quickly becomes cluttered and titles are not shown fully. It is hard to switch between the tabs and when working with a large collection of literature, I miss the kind of productivity, I'm used to when working with multiple files at once in IDEs. Some easy to implement suggestions for the UI: If one hovers at the tab, Okular does not even show hover text with the full tab name (similarly to Firefox). A good solution is also Kate's opened documents list which gives an overview of opened documents.
Will the following patch help? It shows the document title as tooltip when one hovers at the tab. https://invent.kde.org/kde/okular/-/merge_requests/151
