Pretty great Rated 5 out of 5 stars

I love the things this addon contributes visually. A few requests however.

One: having the alternate location status breadcrumb (the one which shows loading status) editable in terms of color instead of the default blue.

Two: Able to change the colors of certain url elements. The default green, while useful, can get annoying and doesn't even remotely resemble my theme.

While functionality-wise this addon shines, there are a few aesthetic changes still needed in my opinion, mostly involving color customization. Just those two changes would make me a very happy member of the web surfing community.

Keep up the good work!

Cheers :)

EDIT:
Heh. Sorry about that. For some reason my eyes must've skimmed that portion about step 10 O.o

Thanks for showing me the error of my ways.

That still leaves me with two more points, however. I don't think the progress chevron is editable if I'm looking at the default template correctly, and I mostly just want to change a few core functions of the dark theme, rather than going through the process of redoing the entire theme.

Regardless I think I can manage and must thank you, the developer, for making an awesome addon worthy of much praise.

This review is for a previous version of the add-on (5.0). 

Hi, please feel free to create your own theme by choosing the colors of your own liking. All this is already possible. Just follow step 10. of the feature list on the add-on home page. Thanks :)

UPDATE: yeah, my bad about not documenting the status bar part yet. But here you go:

To change the color of the progress bar, you can simple open the Options window (Ctrl + Alt + L), go to Progress Bar tab and choose the color of your liking from many options present there.

To change the style of the status bar that appears to the right of the breadcrumb apply any style on the id

UIEnhancer_StatusBar

It has 2 children, first one is the icon (chevron icon) that is displayed to the left of the status text, and the second one is the label that contains the text of the status bar. So you can style both the children using #UIEnhancer_StatusBar :first-child and UIEnhancer_StatusBar :last-child selectors
