Autocomplete: Suggest users when adding a column

[KeziahMoselle]

I thought it would be great to add a suggestions of users to add :

A great improvement of this is an autocomplete on the input with the users's list below.

It can be crossed with #28, if we click on multiple users it adds a list of users to follow in that column.

What do you think ?

I would like to have autocomplete support, yes.

We should probably show it right below the text input rather than below the button like you showed in the mockup.

Haven't played with them yet but there are some popular autocomplete libs out there that could help, e.g. downshift https://github.com/paypal/downshift

Look this github search implementation: https://codepen.io/andreic/pen/oKghp You can search by repository name or username. I dont tell about design, I tell for search mode.
