Interlinking: ability to mention a doc

[virgile-dev]

Feature Request

Is your feature request related to a problem or unsupported use case? Please describe.
Soon people we'll build wikis using subpages.
They'll need to create internal links so that people navigate their content.
Right now they do normal links which is not ideal as when clicked it opens a new tab and you don't have a good navigation experience.

Describe the solution you'd like
I'd like to able to :

• Mention a page @type the name of a page get some suggestions in a dropdown.
• When I add an internal link I want it to automatically convert into a nice snippet with the doc name

Describe alternatives you've considered
A clear and concise description of any alternative solutions or features you've considered.
