Thread:Project:Support desk/Hyperlinks pop-up info

Hello there, I'm an avid wikipedia user and I've recently experienced a certain difficulty to nagivate around a specific topic (new to me), because of the abundance of jargon and terms that other otherwise covered on other wikipedia pages, all leading to a copious number of tabs to understand a page of molecular biology (for example).

What I was thinking is: would it be possible to develop a feature on wikipedia pages where positing the mouse on the in-text link, would automatically (or under request) show a basic explanation of the term without the need to open a new page for the specific link?!

I was just wondering and I'm not even sure if this is the right place where to post this, any suggestion???
