+
+1. library select - so when there are multiple sources, one can be picked.
+2. type select - the type of entity to browse. Will offer up types available for the chosen library.
+3. path/file select boxes - normal file browser type behaviour
+4. import button - when clicked will import the selected entry.
+
+The 'import' button behaviour will depend on the current editor state:
+
+ - in 'normal' mode, import will import the selected flow, or the node of the appropriate type.
+ - if a node is being edited, the 'type' select will be restricted to the required type and clicking import will copy it over to the node edit dialog
+
+**Todo:** what is the `export to library` workflow.
