UI Feedback - Charms Need a UI Visual I can See

Charms are one of the newer aspects of Path of Exile and I for one enjoy the design as it allows me to customize my characters defenses on the fly and prep myself for upcoming battles. I can pause and then equip an anti freeze charm, for example, when up against a tough freezing Rare.

The main issue though is that, unlike Flasks, I cannot see the status of my charm. So i really have no idea if it is out of charges or can't see it gathering charges either.

Suggestions :

Update the main UI to include the charm somewhere around the HP or have a picture of the charm like danging from the healthbar. The charm could glow or something as it gains charges, brighter and brighter and fade as it loses charges, going dark when it is out of charges.
