Description:
With my system colour scheme, the cursor point and text highlight colour is almost invisible in the Writer page.  This is partly due to my using a dark theme in Libre. My page bg is dark with light grey text, and the cursor blinks white, with grey selection.  In some situations this makes work very difficult, such as when searching for something small, like a colon mark, it sometimes takes a minute to find where the selection has landed.

I would like the ability to override cursor colour and selection colour, to any colour that myght work better, e.g. orange and pink.  

And how about Active Paragraph highlight? so that the paragraph currently under the cursor is highlighted with a faint colour (set in options).  Thus it the cursor can always be found on the page, it will not get lost all the time and need scanning to find it.

So on a white page with black text, the para highlight could be a light blue or grey, on a dark page with light text, it could be a dark purple.

For accessibility, it would be great if there was a hot key to press and a briht coloured focus ring appeared around the cursor point (with scroll if necessary). This would be great even for people who have good eyes!

Steps to Reproduce:
1.Select text with mouse
2.click anywhere in text



Actual Results:
Text highlighted with system colour scheme,
Cursor follows system colour scheme.

Expected Results:
I would like to override the system colour scheme in Libre


Reproducible: Always


User Profile Reset: No
