@spwolf Yes. Maybe the first step would just be that you could fill in something like:
.apk=.zip .info=.txt
in the configuration to say .apk files are always to be treated like .zip files and .info are always to be treated like .txt.
Also either
=.zip
or maybe
.=.zip
would mean files with no extension are to be treated like .zip.

It would be nice to be able to configure this on a directory by directory basis but I can’t really see a good way to do that without it also making things rather complicated.

The best I can come up with would be to say that you could store the configuration in a file in the directory with a special name and PA would know not to store that special named file and would instead use it to adjust the configuration. Something like .PAConfiguration
