Can you add title tag field for the 'Login Image' option?

I have the Ultimate Branding plugin installed and when enabling the 'Login Image' option and add a logo, there is no field to replace the default "Powered by WordPress" title tag which appears when people hover over the logo image on the login page.

Could this feature be added please. I have been using the "BM Custom Login" plugin which works well and has this option, but am trying to reduce the number of plugins and prefer to use ones by WPMU if available.

Their plugin has other options like adding a background image or color, change text color, etc but I'm not really needing these, just the option to replace the title tag with my own wording :slight_smile:

Cheers, Ian
