Google Maps bubble size and direction icons


I've met a few issues with the Google Maps plugins, I hope you can help me fix them.

1. How to make the bubble bigger so that there is no need to use the arrows (please see the picture ?
2. How to make it appear by default without having to click on it ?

3. Is the a way to have the directions icons like in the google maps website (see picture) ?
4. How to get the direction in french language like in the google maps website ?

Thank you!
