It would be nice if there was a dedicated field that was metadata about a task that could store a URL and be an actionable (clickable) link. There are more and more time where a task relates directly to a web page of some sort.

Doing so would also provide some initial (simple / low cost) integration with Evernote (reference material related to a task). The Evernote note URL could be stored as part of the task metadata and be a quick link to any supporting task resources stored in Evernote (or similar repositories with direct links / URLs to the resource).
