Minimize by default and resize option needed

Hello,

The plugin works well but there really should be an option to make it minimized by default.

Resizing the plugin window also should be an option, or at least the note about cookies etc. that appears while you sign in should be smaller, the font is way too big now. I tried to override the css setting of the font size but failed. Could you possibly give users at least a little bit of customisation? Thanks.
