I love this add-on, but I rate it with 4 stars because when sitting idle the text is so faint it's hard to read.

Works well with me.
Pretty much what it is in the preview.
I'll probably keep it.

Great look

黒と青がおしゃれです。

Pro: Beautiful highlight color with excellent visibility.

Con: Hover over inactive Tab needs a more noticeable highlight.

Very pretty colours, but the contrast on the tool bar is INCREDIBLY low, to the point of being practically unusable.
