I really like this add on, and very much enjoy creating my own themes with it. But i would like to create and save more than just three. Maybe you could make that possible, dear developers?

I use the Firefox Dark Theme and I really like it, but i wanted change on thing. But this is not possible with this Add-on

nice

I wanted to use it but it doesn't apply dark themes on homepage so I'm not using it. Hopefully you will add the feature to apply themes on homepage as well.

Hello developers. That add-on is cool and interesting but... I'm begging you! Add ability to change color or image of a new tab (tab when you are clicking + (open new tab)) in this add-on. It will really helpful because now when I use black theme with some customization I see white color on a new tab.
