Ability to add "Logged Time" to feature cards, in the same way "Estimate" can be shown.

Currently it's possible to drag "estimate" over to the feature cards (in Features->Workflow).  Our company doesn't use estimates heavily, but we do log rough time taken on a task.

This would allow myself (as a developer) a quick glance to see what I need to fix up, and if the times are a fairly good representation, rather than clicking in each card, or going to a different view.
