Xataface automatically shows the 'details' tab if no other action is specified. This how-to explains how to change this default functionality to make the 'list' tab the default view.
As of Xataface 0.6, this can be done in the conf.ini file using the default_action attribute. As an example, add the following to the beginning of your conf.ini file to make the find action the default action.
default_action=find
You can also set the default action to be performed in the details tab using the default_browse_action attribute. E.g. to change the default action to edit instead of view, you could do:
default_browse_action=edit
