Been using sumatrapdf for awhile now and absolutely love it. What would make it perfect for me would be the option/shortcut to jump to the next/previous document within the same folder, without the need to close the current document and opening the next manually. This feature will be really helpful when reading mangas with tons of chapters.
In the Manual at bottom of Navigation it shows
< Ctrl > + < Shift > + Right = open next document in the directory
< Ctrl > + < Shift > + Left = open previous document in the directory
They should still be working
ah! Foolish me didn’t think to check the manual. That works, thanks!
