Very good add-on. Anyone using more than one e-mail account in any e-mail-client should have functionality like this to prevent the embarrassing case of sending an e-mail from the wrong address. It makes one wonder why the TB team don't build such functionality as part of the core product.

** Warning **
This add-on does conflict with another add-on called "Identity Chooser" (which has its own neat functionality). By default, both add-ons try to colour the header section of your e-mail windows which causes a conflict resulting in multi-coloured composition windows and confusion as to which account you're sending from. Fortunately, both add-ons also allow you to disable the header colouring feature, so my solution is to switch that feature off in Identity Chooser because the colouring features are more powerful in Account Colors.

It would be nice if both developers could get together to create one unified add-on with the best features of both. But that's how it is for now at least.

This review is for a previous version of the add-on (13.4).
