This is related to a request made by @JonL some time ago - about the issue of having to hover over tabs frequently, to confirm files and paths.
I hope this feature can be implemented at some point, but additionally, I think it would be very useful if the current filename could be displayed at the top of the window. I imagine this might be a simpler feature to implement.
There’s plenty of unused space - which could be put to good use, eg:
An option to choose the width of the tabs would be a great option too - particularly for wide-screen monitors.
