+Leverging FZF for a user interface one can do fuzzy searching with a directory tree and document preview. 
+
+The PTF.py creates that tree then colors the path thus giving a graph of the item searched.
+
+Example Usage includes:
+  - More advance Poorman's Mindmap
+  - Person/Contact Graph as a filesystem
+  - Asset Mapping (with pass(1) and LDAP file system structures)
+  - Maps with stow
+  - Project Management / Kanboard
