It seems that recently the interface of the <languages /> output was changed for some reason and instead of the coloured boxes now there are circles to indicate the translation progress.
While I don't particularly mind squares to circles change, though as someone with myopia I was finding squares more easy to discern, for the same reason I do mind the lack of colour coding. Now I have to look closer to the screen to understand what is the translation status, whilst before I could understand that from the colour.
Thus, I suggest keeping the circles, but I would love to have the colours back. Perhaps it can be an optional setting or something, and perhaps colours can be different too (e.g. to match Wikimedia colours better). But just having everything in blue is awkward to use for me.
