Request for additional theme UI settings

[cydonia]

In cudatext version 1.214.6 Options->Themes->Settings - theme - ui... there is an "tabs, font, modified tab" option to set modified tabs font color but theres no "tabs, BG, modified tab" to set the background color likewise theres no "tabs, BG, read only" nor "tabs, font, read only" options, could I please request these options.

I add new colors only when needed, each color adding needs the themes updating (also for themes in addon-manager).
i think users can live without "tabs, BG, modified tab".
font-color is enough.
ui-tab shows DOT for modified tab, also makes it enough.

for "tabs, BG, read only": even more work is needed, so I want to avoid it too.

plugin can change the tab-color via
ed.set_prop(PROP_TAB_COLOR, 0xff)
