Delete mirrored nodes hotkey.

Hi Workflowy team, I would love a hotkey to delete all mirrored nodes without having to click through "...", "Node has 3 mirrors. See them", and then "Delete all".

I use mirrored nodes all the time (the main reason I started using Workflowy over other note keeping programs), and a hotkey (maybe Alt + Shift + Backspace) would make things a LOT more convenient.

It would also be fantastic if the hotkey worked similarly to the Ctrl + Shift + Backspace, where I could select multiple nodes (mirrored or not) and delete them all (including all of the connected mirrors) with Alt + Shift + Backspace.

Keep up the great work, thanks.
