My colleagues and I are developing wiki using your framework and were looking for a feature that exsits on Wikipedia. The pop-out information box that appears when hovering over a link to another page on the wiki (see attached photo).

This would be very valueable in order to give readers small nuggets of information about relevant/linked terms or concepts without them having to leave the page they are currently browsing.

We believe this will be a very usefull feature for many users, and in particular for the readers of the wiki!
