I use a couple of filters to label certain files. For example: The filenames of .pro files are red, and .jpg files are green. I also highlight files that are changed within the last hour.
It is possible for more than 1 filter to be true, for example if a .jpg file is modified within the last hour.
What filter is used now?
Can I assign priority for certain filters? For example the top most filter in the list that matched a file is used to color that file.
Maybe it would be nice if more than 1 filter matches a file to combine the labels somehow? In that case the filenames of .jpg files would still be green, and the background color would be yellow.
Wildcard labels always beat filter labels. There's no way to adjust the priority at the moment (it's on our list for consideration in a future version).
One workaround is to use filter labels for everything, and make them all mutually exclusive. For example, your .jpg color would use a filter which only matches *.jpg files which are older than 1 hour; then it would not conflict with the filter for files modified within the last hour.
