Rated 2 out of 5 stars

This add-on restructures the whole TB interface in a too simplistic way which impairs productivity. Recommended only if you don't care about productivity.

The main points I dislike are:
1. . .no "reply" button
2. . .no "delete message" button
3. . .interface bloated with useless buttons
4. . .useless inline quick-reply form. I use Quicktext 0.9 to aid email writing and deploy templates. Inline reply is just useless
5. . .the UI is mostly not customizable, except for minor (useless) details
6. . .unpleasant color scheme: orange, red, blue, gray, light blue. I dislike it.

I would suggest to introduce /way/ more customization options in the add-on settings tab, to best fit everybody's needs or tastes.

Features I'd like to have, either available by settings or by default:
1. . .comprehensive UI headers, soberly showing email subject, source and destination address
2. . .sober buttons, showing /both/ icon and text label
3. . .no CSS shades or blurred round bar effects
4. . .more sober, accessible, and customizable UI

This review is for a previous version of the add-on (2.8.1).
