Client-side Link History page
Context
people who use Flink, tend to shorten multiple links. A feature that shows them which links they have shortened in the past would be handy. The shortened links are stored in the local storage of the browser. A page is created that lists all entries in the localStorage of the browser. Everytime a new link is flinkified, a theme adds an entry to localStorage.
This is a client-side (as-in frontend-only) feature. No ASP.NET Backend code needs to be touched, just HTML, CSS, and JS.
