User interface resources
Most Splunk apps consist mainly of resources for the web application. The app layout for these resources is completely different from all other configurations
Views and navigation
.conf files, view and navigation
documents take precedence in the following order:
$SPLUNK_HOME/etc/users/$username/$appname/local: When a new dashboard is created, it lands here. It will remain here until the permissions are changed to App or Global.
$SPLUNK_HOME/etc/apps/$appname/local: Once a document is shared, it will be moved to this directory.
$SPLUNK_HOME/etc/apps/$appname/default: Documents can only be placed here manually. You should do this if you are going to share an app.
.conf files, these documents do not merge.
