Styles of multiple matching Label Filters aren't merged

Any progress here?
Do you consider adding some kind of label filter merging or prioritizing as described in different topic?

I would prefer merging at first glance. But I'm not sure if it's easy or even possible to make.

Anyway, I would like to have an option to indicate that file was modified within nn hours - by changing icon color.
And mark files manually by changing their font color / background / style.
