@randomgeek Ooooh! Split views! I've often thought that could be desirable. I've been using Sumatra PDF for a long while on Windows for its tabbed views. Sumatra will also restore tabs between sessions (handy when you have to too many datasheets open at any given time). Does STDU Viewer restore your session?
A bunch of technomancers in the fediverse. Keep it fairly clean please. This arcology is for all who wash up upon it's digital shore.
