description for "ui_lexer_themes":What's the difference? I don't understand the purpose of ui_lexer_themes.
Allow to apply color-theme to lexer's styles.
So it allows to apply colors from mentioned dialog - to the lexer styles. e.g. Rainmeter styles.
option on: lexer styles are overwritten from current syntax theme.
option off: current syntax theme is not used (except maybe 'SeparLine' item).
