CloseReview for Highlight External Addresses by T V
Rated 4 out of 5 stars
First of all, thanks for this extension. I have been looking for something like that for quite some time.
The main issue is that it only works for plain text messages right now (version 1.03). If I compose an html message, I do not get the address highlighting.
Also, (in plain text obviously) the highlighting happens even when the recipient line is still empty or unfinished. This is a little bit annoying. Having the highlighting happen only on completed recipient lines would make it even better.
