The following is a matter of opinion. My opinion - so please, I am not soliciting debate.
Re: your sig and avatar, I have to admit. Damn, you're good
I bet you could make some great browser icons utilizing the colors and style of your avatar and sig. I see icons along the lines of your yin-yang with a touch of gold used in your avatar's lettering (*which will render a elegant look as opposed to plain metallic) - part metallic raised and cutout showing background of toolbar perhaps when you click on them they render a push-button effect -perhaps using typical icons such as "home" as a template (but more Mac style without the detail of windows icons). It would make a very elegant browser toolbar.
I also think it would become number one or at least one of the top downloads. Look at the present numero uno: https://addons.mozilla.org/themes/mo...&page=previews - it's candy. Too much color. It lacks elegance. This is exactly what browser toolbars are missing - elegance. I don't want to see a cartoon on my browser toolbar. I want champagne and caviar styled elegance.
Judging from your work, you are an artist and you know what I'm saying. I know you do. The browser toolbar should be a beautiful frame not the showcase. Icons should be all uniform - identical in color and size yet easily distinguishable. It should not distract from webpages yet function as it's intended purpose - a toolbar. I believe this is the same format Apple follows if you notice Safari's toolbar.
Take a look at the top Fx themes. Do you see any elegance at all? - https://addons.mozilla.org/themes/sh...ry=Top%20Rated
