Annotating editor title

Hi,

Given that many Gradle projects use the file named "gradle.properties", I
wish that users having multiple "gradle.properties" opened be able to
distinguish them. What I prefer to do is to annotate the title of the
editor tab with the directory name containing this file (similar to how
pom.xml is). However, I don't want to change how "gradle.properties" is
treated as it is a simple properties file otherwise. Does anyone know if it
is possible to only adjust the title and not any other functionality
associated with properties files?

Thanks,
Attila Kelemen
