[neomutt-users] Too few arguments on folder-hook

[Kenneth Flak]

Hi Rich,

The fix you suggested works beautifully. However, when this is enabled it takes neomutt around three seconds longer to launch than when it is disabled. Is this expected behavior? Alternatively, is there a way to run this command asynchronously?

Best, and thanks so much for your work on neomutt!
Kenneth
