SUMMARY (Sorry if this is mis-filed!). I dislike the default alt-tab visualization. After browsing settings, I finally found Window Management -> Task Switcher, and "Visualization." Personally, I think "Breeze" and "Breeze Dark" are pretty poorly named, since they provide very different visualizations not tied to the color. For example, I prefer "Breeze Dark" regardless if I'm using light or dark colors. I really don't agree with the justification that light vs. dark even warrants a separate visualization (why not just use the same default for both?), but that's probably a different argument :-) Any thoughts on simply renaming these to something not tied to light & dark theme?
I agree. IMO There should be only one and it should follow the Plasma theme's colors, and it should be called "Sidebar" or something like that.
Partially fixed with https://invent.kde.org/plasma/kwin/-/merge_requests/3436. With that, there will no longer be a "Breeze Dark" task switcher. There will still be a "Breeze" task switcher until we rename it to something like "Sidebar". See also https://invent.kde.org/plasma/plasma-desktop/-/issues/53 and https://invent.kde.org/plasma/plasma-desktop/-/issues/63
This Task Switcher has been renamed to "Sidebar" in Plasma 6 (and moved into the kdeplasma-addons repo).
