Better visible underlining

The issue: It is easy to overlook the blue underlining, for example in the case of double quotation marks.

Is it possible to change it slightly - for example, to be wider and/or more glaring?

You could add a coloured background to error messages. For the procedure, refer to ‘Show error types in colour’ (Install the term checker for ASD-STE100).

Are you using the stand-alone desktop version or the LibreOffice/OpenOffice add-on? Mike’s suggestion will work only for the stand-alone version.

Thank you, Mike and Daniel for your quick answers.
I use LT as an LO’s extension.
