Rated 4 out of 5 stars

I love this add-on, have been using it for several years now, and it is among the first add-ons I install on every Tb instance. Though, I mainly use it for its S hotkey. ;)

However, there is one issue I have with Nostalgy: In my opinion, the hotkeys should *only* be active when in Tb's mail context, e.g. on the mail tab. Hotkeys should do nothing when in Lightning/Calendar view, and even less so when in Sieve message filter editing mode!

I find it really annoying that, when writing Sieve mail filters in Tb (add-on "Sieve", https://addons.thunderbird.net/en-US/thunderbird/addon/sieve/), every pressing of a S, C, G, and other keys, let alone their Shift-Key versions, Nostalgy reacts with some unexpected popup and I'm hindered from editing my filter rule. Please, fix this!

This review is for a previous version of the add-on (0.2.36).
