But do you see that title bar buttons are bad explicitly because you have to hunt for title bar edges?

That you were more or less forced to adopt these KDE shortcuts so that you could work around the fact that they had cannibalized the title bar for a purpose it was not designed for.

You were forced to change your workflow and everybody else is having to be forced to adapt because they changed a metaphor that has remained stable on the desktop for over 40 years

My main interaction tool with the system is the pointer. Reaching out for the keyboard is something I do when I want to type, but for example when I am consuming content on my computer I just keep a single hand on the mouse or the trackpad. In that case shortcuts are just plain annoying.

On KDE, something nice is that if you have a maximized window and a pane on the top of the screen, I can drag that pane to grab the window (or maybe it was a setting of Latte dock or something). And since window titlebars nowadays can be cluttered with buttons, it is a predictable way to grab those windows only using the mouse.

The reason they have to put all that crap in the title bar is because of all the other bad UI decisions that used up all the screen space.

fwiw, when I'm on an OpenBSD desktop, I use cwm which doesn't supply titlebars, and I use Meta+click to move windows. That's great...On OpenBSD. But sometimes I'm using a Windows computer. Sometimes I'm using a Mac.

...And sometimes I'm using OpenBSD, so titlebar buttons introduce a titlebar I didn't want, and didn't need, which doesn't match the rest of my desktop customizations.

It's just a bad paradigm.

There's a lot of mouse centric workflows, where you don't want to keep switching between mouse and keyboard all the time.
