To me, the big aesthetic of early Qt/KDE1 is "Obvious Motif ripoff". Aside from the Win95/Warp style titlebars, if you don't have the big thick bevels and the distinct scroll bars, it's not quite right.

It really galls me that they removed the Motif style in Qt6, since I target that as my default look and feel. It gives a nice "This is expensive professional software with a codebase tracing back to the Reagan administration" vibe.

There are themes that come close in various attempts-- "Commonality" for Qt6/Kvantum, and some of the assets from NsCDE for GTK, but it feels like a pitched battle against design teams that desperately want to mimick whatever Apple is doing this week.
