It’s fair that the core app still compiles and has some maintenance, but there hasn’t been work done on the plugins and system integration in about a decade. What’s left makes a nice but slowly decaying launcher. The magical workflows of being able to navigate swiftly between app context menus, system services, and web services without a mouse or even leaving QS...those are but memories.
QS circa 2008ish spoiled me for all launchers since.
