I'm new to both Raspberry Pi and Linux, but looking to setup a Pi with JMRI. I have successfully done so with one exception.? By default. the JMRI install creates a hidden directory? called .JMRI as the location for user files like scripts. I tried to create a new directory .DIckens to store my files. When I tried to change the preferences to point to this location, JMRI wont show any hidden directories that start with a dot for me select or navigate to. Is their a setting I need to change to get JMRI to see hidden (.) directories?
