Thunderbird's tags numbers 7, 8 & 9 are overwritten

[emv-prx]

FollowUp-created tags use IDs 7, 8 and 9 of Thunderbird's key-shortcut. I.e. previously to have Follow-up installed, by typing key '8' my own tag was assigned to the email I was on. After installing Follow Up by typing '8' a tag called "due xxxx' is assigned

Otherwise, great add-on
