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.
I think most PDF readers support Javascript. I use xpdf and one of the reasons is that it does not support Javascript.
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.
