This was brought up in the topic https://ask.libreoffice.org/t/change-wavy-line-to-text-highlight-during-spell-grammar-check/78483/3 in The Ask site. Some visually impaired people have trouble with wavy underlining and would be happy with a colored background. So - could you add an option to highlight text instead of wavy underlining it?
Sounds a good idea to me. Let's hear from the UX team.
Could be an option similar to what we have for track changes (tools > options > writer > changes). Objection to another rather complex option?

IMO this is a good idea. The new options dialog should be under Tool - Options - LibreOffice - Language Settings, so that it is applicable to all LO applications. Heiko, we should also give the option to keep the existing behavior (wavy red / blue lines). Also, the dialog you gave as example allows to define the text "Attributes" and text "Color", but it would be nice to have a "Background color" as well, so that the highlighted text stands out even more. This way we could have an implementation closer to what was suggested in the ask.libreoffice link (see Comment #0), which looks nice IMO.
