Gtkpass is a simple GUI for the pass password manager written in Python and GTK 3.0.
The configuration file is looked at $XDG_CONFIG_HOME/gtkpass.yaml and is in yaml format. Currently there is just a plain list of options with their defaults:
save_dimension: false
confirm_recursive_delete: true
confirm_delete: true
height: <unspecified>
weight: <unspecified>When save_dimension is set to true, application will save dimension of the window into height and width, and pick it up again on program start.
Confirmation are always enabled, as deletion will be instant. Of course, as pass is git based, there is always possibility to get deleted items back, but it should be such question, and both of them can be silenced.
