Rated 4 out of 5 stars
Excellent add-on, very useful and handy.
One feature missing on my opinion : keep location of selection (or cursor) when switching between tabs, and auto-scroll destination tab to selection.
For example : I need to clean up some formatting code in the middle of a very large message, when I switch to HTML tab, I need to scroll carefully from beginning of content, all the way through a lot of CSS and Tags, to reach the part I want to edit,
Such feature would ease the browsing of the code, and help overlooking selections such as tables or lists...
Thank you for reading, best regards
