Hi! Thanks a lot for your contribution, although I'm not sure about the
implementation.
The solution for the excessive indentation is nice and elegant (and I've
already put it up in production) but I don't think we should hide the whole
sidebar in a mobile view. I realize though that just for the purpose of using
the forum your solution works great, but as you and adfeno both have said, we
would have to put the contents of that area elsewhere, or made them available
at a hide-able menu.
I'll look further into it, although with the plan to migrate to a better
solution for the website & forum (which should take care of all these issues)
we shouldn't probably invest a lot of effort on fixing the (admittedly not
that minor) problems with the current layout.
Thanks again!
