Part Library browser cannot access hidden directory below "~/.local"

[wolfgangr]

• installed part library using addon manager
• called macro as instructed
• can browse file tree, but not access part library location
• opening part library in addon manager, I find the installation path: /home/username/.local/share/FreeCAD/Mod/parts_library but cannot open this location, since directory names starting with a dot are hidden in standard GUI
• don't know how the file browser of the GUI is configured, but I can't find a location to enter/show hidden directories
• workaround: create a non hidden symbolic link, e.g. _local_share_FreeCAD -> /home/username/.local/share/FreeCAD
