Sorry I missed this post.
1 - Is there a way to display labels icons into SCLogin username/password fields like for the joomla standard login module ?
There's a lot of arrows on your image. I'm not really sure what you mean by this one. Can you explain this a bit more?
2 - Why the SCLogin module fonts size are differents (bigger) than the Joomla standard login module (that follow the default joomla template) ?
We have our own styles for the SCLogin module and try to inherit what we can, but set a lot automatically. This has proved to be welcome for many users for a consistent style, but we can help you if necessary.
3 - Why the "?" icons (username and password reminder buttons) are bigger than the respective fields ? How to have them follow the same fields dimensions ?
This will be fixed in the next release, planned to be available on Friday.
Thanks,
Alex
