AFAIK the Same situation with KDE Connect which I couldn’t properly exist without. Also KRunner & Dolphin. Kate would be possible but hard AF.
Full on agree with KRunner. One of the MVP applications of KDE. So far none of the alternatives I tried on Windows 10 and MacOS come anywhere close to its power and elegance. Maybe Alfred which I tested years ago.
I could write 10 more paragraphs about why KRunner is one of the most advanced laucher/search/command application but I think everyone should experience it themselves. Best not to over-do it with the KRunner-plugins where an overwhelmingly long search result list could ruin your experience.
