Hi,
I just wrote a PDF reader based on Chromium PDF engine.
It's pretty dummy, written in 30 minutes. But quite useful (at least for me) given the limitations of Document viewer, and that sturmreader is currently broken on noble.
I think it will greatly benefit from Qt6 upgrade, when it comes, because of improvement of the engine in chromium.
It is published in the openstore:

Regards,
Pierre.
