>"So instead of fixing the constant bugs and crashes, you're hardcoding a "feature" we already had with plugins? This isn't an improvement; it's a step backward. We used to have the *choice* to add these effects. Now you're forcing them on us and removing customization."
They are not removing the choice to turn that feature off. But they are removing the choice to remove the bloat of the code, that is true. I am not sure why they would do that. Personally, I think rounded windows are a silly fad. They could have just included the plugin as a default with it on and easily turned off AND removable.
>"Focus on making KDE stable, not on trivial visual garbage."
Unfortunately, "eye-candy" seems to be the major focus of so many projects (software, desktops, websites, etc). And it often comes at the cost of customization and focus on more important stuff like performance, battery life, time, usability, function, bug fixes, etc.
Look no further than the horrible UI disaster of Gnome 3+ for a perfect example of forced radical UI changes that most people didn't (and probably still don't) want. Gotta hide everything. Gotta get rid of menus. Gotta get rid of icons in menus, round everything, full-screen everything, white-space and space-out everything, monochromize everything, "fade in/out" everything, "smooth scroll" everything, take over the function of window titles, restrict themes to death, and on and on. But the developers "know better". At least KDE and most other Linux desktops respect choice more.
