+The ~denote-silo~ package helps with this by prompting the user to

+The ~denote-solo~ package by Pavlo V. Lysov takes the opposite stance:
+instead of prompting for a directory on every command, the user picks
+one - a *solo* - once, and every subsequent Denote command operates on
+it until the user switches again.
+
+The active solo is remembered across Emacs sessions and shown in the

+keyword completions do not leak between collections. Toggling back and
