 The only issue with noice is hard-coded file associations. There is no config file (better performance and simpler to maintain) and one has to modify the source to change associations (see [how to change file associations](#change-file-associations)). nnn solves the problem by adding the flexibility of using the default desktop opener at runtime. There are several other improvements too (see [fork-toppings](#fork-toppings)).
 
+You can try
+
+    alias n='nnn -d'
+and see how nnn simplifies those long desktop sessions.

 Have fun with it! PRs are welcome. Check out [#1](https://github.com/jarun/nnn/issues/1).
