A problem I had with using rikaichan (firefox extension) or rikaikun (chrome extension) on LingQ is that the spacing often cuts phrases that the extension would have recognized, in two. The “show/hide spaces” should remove them instead of hiding. I solved this by making a bookmarklet that I click instead of the “hide” link:
javascript: var $s = $j(“span.whitespace”); if($s.first().html()==“”) $s.html(" “); else $s.html(”");
Just create a bookmark with that as the URL in the bookmark bar or whatever.
