You're welcome!

Thank you Chris,
I am adding it to my to-do list.

On Options Hotkeys Apply, the confirmation message that appears when the hotkey is already in use is faulty. e.g.

1 In list, click General: Go to the Genre node
2 In Hotkey:, enter CTRL+ALT+0
3 In Action:, enter Filter: Podcasts
4 Click Apply

MM says:

. "CTRL+ALT+0" is currently used for "Rating now playing track: Rate 0 Stars".
. Use it for "General: Go to the Genre node" instead?

instead of

. Use it for "Filter: Podcasts" instead?

as expected. Note: the fault is in the dialog only, and not the effect of the operation itself.

Likewise, when the equivalent sequence is carried out on <New Hotkey...> the confirmation does not identify the new action, e.g. says:

. "CTRL+ALT+0" is currently used for "General: Go to the Genre node".
. Use it for "<New Hotkey...>" instead?

I suggest it would be better for it to identify the new action.

EDIT Fixed in 1304.
