I need to change backgroud color of the marks, but I can't find this option in menu Settings -> Style Configurator.
Create new tab, insert text "hello world!", press Ctrl+F, go to "Mark" tab, enter "world" press Find All.
The word "world" marked with pink background.
How to change this color?
In the Style Configurator, in "Global Styles" it is the "Find Mark Style". By default, the background color is red, which looks pink when drawn with transparency over white.
