Do responsive the Refworks site
Currently the user interface and login site are hard to handle trough mobile devices.
I suggest a user interface auto adaptable to device screen (responsive)

For example on a side by side view on Windows, the viewport is small in which case all the buttons at the top bar overlay the some part of the reference list that one cannot select the ones overlayed without maximising the browser window.

Accessibility for mobile device users is an important issue for our students. They tend to regard mobile responsiveness as a default feature of any library promoted service.
