Nice but not on mobile

This is a very swish plugin for login/register operations. It works well and looks great.
That is except on a mobile! It gets in the way and its some of its featured operations just off screen on an iPhone.
If the plug in cannot be made mobile friendly then it should at least have an option to check to exclude it from mobile deployment. I was going to post this in the support form for it on this site but see someone has with no replies at all. Support seems quite lax?
Im looking to replace it now unfortunately
