Looks good to me too!

My only gripe would be that it makes it a bit harder to add new
commands, since it now requires modifying both project-switch-commands
and project-prefix-map. Maybe we could reintroduce the helper function
we had for that purpose earlier.

-(defvar project-switch-commands
-  '((?f "Find file" project-find-file)
-    (?g "Find regexp" project-find-regexp)
-    (?d "Dired" project-dired)
-    (?v "VC-Dir" project-vc-dir)
-    (?e "Eshell" project-eshell))
-  "Alist mapping keys to project switching menu entries.
+(defcustom project-switch-commands
+  '((project-find-file . "Find file")
+    (project-find-regexp . "Find regexp")
+    (project-dired . "Dired")
+    (project-vc-dir . "VC-Dir")
+    (project-shell . "Shell")
+    (project-eshell . "Eshell"))

The project-shell command is added here, don't know if that was
intentional?

Also why not stick with the easier extensible list format? I could
imagine for instance adding long descriptions as an optimal third
element for the commands later on.
