Something semi related, I have a userscript that shows other definitions of a word and it loads instantly when I hit 'f', unlike wanikani which usually takes 10 - 20 seconds, however wanikani throws a 50% grey over the information area while it struggles to find its own information so I struggle to read it for a second. Maybe just a simple CSS thing, but does anyone have any ideas? Thanks.What is this userscript called? I can't seem to find it. Is it one of your own (unpublished) scripts?
I made a script recently that sounds very similar. /t/UserScript-WaniKani-Quick-Info/8431/1
I think the jQuery command $("#additional-content-load").hide() might be what you are looking for.
