I read a lot of PDFs, and I cannot find a good reader on Linux.
Evince does not support tabs and has no history navigation (back/forward). Qpdfviewer does have those features, but lacks proper text selection. Okular requires a big installation and KDE libraries, which are fine if you use KDE, but I don't. There are many other minimal readers, but they are too basic for my needs. Session persistence in a PDF reader would be nice too.
Which one do you use? How do you like it?
I think there is big room for improvement in this space. Nothing comes close to PDFExpert on the iPad...
