UX: faceted filtering is far too well hidden

[ghost]

It is really hard to find faceted filtering -- the only visual indications that it exists at all are:

1. There is a gray, non-descript panel to the left with a little hover effect. (Or on the bottom in narrow-screen mode.)
2. There is a screenshot of it in the help.

Please add an icon for this functionality to the side bar.

True, the UX isn't the best here. An icon or something would be handy.

This would actually be a feature request for Screenful, the UI framework that Terminologue is using. The relationship between Terminologue and Screenful is explained here.

I should have read your doc first -- and I misremembered my changes as being part of pretty-small.js, but they are actually in screenful-navigator. I'd actually started to create a patch for this (as you can see from my commits above) -- 4b6d4b4 basically works but it is buggy: it looks a bit foreign in the toolbar, it's not always presenting state correctly, it's shown even in sidebars that actually have no facet filter, and I don't think it can be localized. If I get to fix all these things, I'd create a PR, if that is ok?!

(My fork has a few more things, mostly CSS changes [we have too many main languages] and German l10n that I'd like to submit at some point.)
