Sometimes it is necessary to redact a document before sending it. To do that with Okular right now is: - set highlighter to black - highlight Text to redact - draw black rectangle over images to redact - flatten document with Ghostscript, so text can't be marked anymore This has some obvious drawbacks: 1. As a multistep process, it's relatively easy to forget, for example, the flattening afterwards. 2. The flattening affects the entire document and makes all text unmarkable
This seems like a decent quality of life feature that would only simplify features that already exist
