Rated 5 out of 5 stars

The conversation view looks great. It's a pity that when Dark Reader is also installed, Dark Reader doesn't work and the emails remain in the original theme.

The author is aware of this issue and there is a GitHub bug open since 2021 (https://github.com/thunderbird-conversations/thunderbird-conversations/issues/1609). But it seems that the bug is created by Thunderbird and not this extension. So it may still take longer to happen.

This review is for a previous version of the add-on (4.2.2).
