Is there a PDF viewer/reader that supports JavaScript like Adobe Reader?
For example for D&D I use the MorePurpleMoreBetter character sheet that uses tons of JavaScript to automate many things.
Right now I’m using the Adobe Reader snap package that runs it via Wine.
Okular has JavaScript support. I think some things don’t work, but it’s worth a try.
Also, Adobe Reader had a native Linux version, so I wonder why the Snap is using Wine.
