I am using KDE Neon, and I have successfully configured Okular to add a digital signature to my PDF (using Tools > Digitally Sign menuitem).
However, it looks ugly like this (the rectangle with black border and light grey fill):
(I added some black rectangles to censor some sensitive info)
Is there a way to customize this ugly representation of the digital signature? I figure to have only the "Signed by:" line and "Date:" line, both left-aligned, will be enough.
