You forgot to specify any reviewers, so I added them for you. +1 from my side, removing code while improving the user experience is always a good thing :)

Very nice looking 👍🏻

In the abstract, I think this makes sense, but in testing, I ran into two issues:

• This has the effect of making the default label width/grid spacing significantly narrower
• Because the label width doesn't take into account the font size (currently as well as with your patch), people who increase the standard font size to 11 or even 12 pt are going to be irritated when more of their file names are split across lines because their labels are narrower than they used to be. Crank the font size up to 15 and the result is... interesting. It's a pre-existing issue, of course, but it becomes more urgent to fix with this patch.

For item #2, adding the font metrics into the calculation should suffice. For Item #1, Perhaps we should normalize the new calculation such that it's roughly the same or only slightly smaller for the standard Medium label width. I don't hear a lot of users complaining that the grid is too loose right now.

Screenshot please? :D

There are videos linked in the summary.

Can we please move this patch into Gitlab over at https://invent.kde.org/system/dolphin and continue the work? :)

I think this can be abandonned after https://invent.kde.org/system/dolphin/-/merge_requests/89 landed.
