Yes ... Since quickbuttons is used in other areas I should have add the clear: both to target only the lower nav area (still a bit fragile, would be better with an id on that nav but ....) So adding
nav > .quickbuttons {
clear: both;
}
and pulling that clear: both out of quickbuttons (that 1.1.4 will add) should fix the issue ...
So now the question, we have a few niggly things found in 1.1.4 ,,, shall we update it before release?
