    The best way to align it would be to add:
    ```
    vertical-align: middle;
    display: inline-block;
    ```
    To the button style and remove the `btn-group`
    Otherwise the button's borders are removed when hovered:
    <img width="287" alt="screen shot 2016-01-22 at 5 31 00 pm"

    There is also the same problem with the last element of the button-group 
(because of tooltip)
    In that case, we might want to add `tooltip-append-to-body="true"` to that 
export button, and this in a css file:
    ```
    .tooltip {
      z-index: 11000;
    }
    ```
    Somebody else, might need to double check all the z-index after that though 
(I didn't found any problem, but I might not have tested everything)
