Mozilla has pdf.js which would be lovely to have inside drive

@uservoice67 There are not enough PDF libraries out there. Monoculture like the one created by the Ghostscript team makes everyone vulnerable by a single library.

When you implement this feature, do not use Ghostscript at all; too many serious security flaws in it.

Being able to visualize bigger pdf files

Many other readers fail to limit potential IP tracking within documents, some documents contain malicious code, and another issue is that temporary data generated during opening is always stored on the C drive and cannot be moved, rendering encrypted drives invalid. I hope Pronton can resolve these problems

arn't there 100 different pdf viewers out there? There must be one that is open Source licenced so Proton can copy paste it in right?

It would be a game changer feature to have the possibility to modify a PDF document directly in ProtonDrive, like what kDrive from infomaniak is (very well) doing !
