I’ve setup okular signing and it worked, but I believe it was with a mime certificate tied to my email (and not pgp keys). If you want I can try to figure out exactly what I did to make it work.
Briefly off the top of my head, I believe it was
Getting a mime certificate for my email from an authority that provides them. There’s one Italian company that will do this for any email for free.
Converting the mime certificate to some other format
Importing the certificate to Thunderbird’s (or maybe it was Firefox’s) certificate store (and as a sidequest setting up Thunderbird to sign email with that certificate
Telling Okular to use the Thunderbird/Firefox certificate store as the place to find certificates
I can’t remember if there was a way to do this with pgp certificates easily
Okular can digitally sign, invert colors (poorly hidden away so you need to customize the toolbar, but it has multiple ways, which is kinda cool).
TTS yes, but there seems to be progress. There is speech-dispatcher which could be used with piperTTS
Okular has no tripple click for whole line selection.
Other than that, setting up digitally signing with Okular never worked for me. Do you have a guide that worked for you?
