Default list is “*.doc;*.docx;*.xls;*.xlsx;*.pdf;”.
After changing the list, quitting the app and restarting it, the list is back to default.

It would be nice if:
1. the list is saved between application restarts
2. the list by default also fits photography files:
*.cr2; *.tif; *.tiff; *.jpg; *.jpeg; *.dng; *.psd; .BridgeSort; *.xmp;
