Thank you for getting in touch about this. Layout is also off in some foreign languages, so we have designed a completely new, more flexible layout for our next version. (I’m not too sure why the layout is off on your site, actually – you seem to have a wide login screen – but the new version should fix it.)
The new version of the plugin will also be translatable, and we are looking for volunteers to translate into their languages.
We should be releasing it this week, and you should be automatically notified in your admin panel as usual.
Please look out for it and email me if it doesn’t solve your layout problem.
