Look, I’ve never used Apple’s quick look or Gnome sushi so I can’t answer this question. The people here can definitely give you a better answer than me haha

After reading about a user who was looking for an alternative to Apple’s Quick Look and Sushi Gnome I decided to create this program to practice with python and make someone happy. I didn’t expect there were so many people with the same need.

It looks absolutely great and I will download it, but I have a question, what advantage does it have, for example, to use this instead, for example, to open Okular to view a PDF?

I think its usefulness lies in the ability to scroll between files (even of different types) with the arrow keys, plus being fast.
