"Save and Apply" does not apply
In all the versions of Turris I tried, from branch 3.x to 5.x, when I save and apply some settings in luci-app-rainbow (for example I change the colors of the wan led), the setting is not applied until I manually restart the rainbow service from the command line (/etc/init.d/rainbow restart). The current behavior of "Save and Apply" appears to be that of "Save".
