Summary: When there is a link in a text cell (and formula cells), it will be rendered with a little clickable icon wrapped in the anchor tag with a proper link. Only links that starts with https? will be rendered as links. Links are shown in a Text and Formula fields, inside a GridView, CardView and in the Import preview dialog.

// The best one was http://alexcorvi.github.io/anchorme.js/, which still wasn't perfect.
|
|
// The best non regex solution was https://github.com/Hypercontext/linkifyjs, but it feels a little too heavy.

// Some examples why this is better or worse from other solution:
