There is a new open source PDF viewer called sioyek that has many of the features of sumatra and has experimental linux builds.

I like the idea of the 'portal' feature. I use a wide monitor instead of two monitors, so two windows side by side is perfect for PDFs.

What is the origin of the name? Sounds pretty hard to remember

Replying here because I couldn't reply to your other comment (I think it reached max depth).

It has no particular relation to PDFs :D. It's just a random name. I also like the number 31.

It means 31 (thirty one) in persian.

And what connects 31 to PDFs? Just curious honestly. I also wonder why Sumatra is called that way
