THANK YOU!
Over the past few years, UI design has been trending towards removing ALL visual cues of how to interact with software and programs. It's intensely weird that we are actually making computers HARDER to use, not easier. Need some examples? Okay!
* Menus containing frequently-used program functions are hidden away behind abstract, arbitrary icons. * There is no separation between parts of a UI that do different things. It's all "flat." * Buttons that perform actions are just text now, and usually look like all other text on the screen. * Icons are now all monochrome, except for branding purposes. * Scrollbars, when they even still exist, are thin lines that only appear while you scroll, making them effectively useless for grabbing with the mouse to quickly navigate through a document. * On Windows and GNOME, titlebars are effectively no longer a thing anymore. Each program implements their own, leading to an inconsistent look and behavior between applications. The only explanation that I can come up with is that most developers these days either use tiling window managers or just fullscreen every application.
Lack of window borders is another item on this list. My monitor is quite often filled with overlapping windows and lack of border means it's often hard to tell at a glance where one window ends and the other begins. Shadows can help sometimes but aren't as useful for "dark mode" or windows with dark backgrounds.
KDE is better than most other desktop environments about retaining useful desktop functionality while all the others are trying their damndest to throw it all away. I hope this makes it into a release!
