Just what I needed after the update to Thunderbird version 78.4. Thank you for updating it.
Unfortunately It appears that either I do not understand how the Hotkey "E" is supposed to work or it does not work. If I type "E" with a message highlighted nothing happens.
When I right click on a mail the menu appears, typing "E" with the menu open requires typing "E" twice since "E" is already assigned to "Edit as a new message".
Also I do not see the Options menu for this add-on in the Add-on Options sub menu.
