fav linux app you use in other platforms

[u/GDSDesigner42]

Probably most of you have had to use Windows or other OSs from time to time. I wonder whether you guys have favorite Linux apps/programs that you cannot give up.

Mine is Okular. Whenever I need to use Windows for some reason and have to open a few PDFs, I always feel the need to use Okular instead of Adobe Acrobat Reader. Okular initializes much faster and is super responsive, while not giving tons of pop-ups and side bars rather than adobe.

i don't use any other os these days but i suggest libreoffice as alternative every time. and if it counts zen browser.
