Panel plugin for Prometheus alert manager

hey Guys,

I have created a panel plugin for viewing the alert manager alerts in grafana.

I would like to use this forum to share my plugin and get some feed back.

This plugin is an initial draft.
Below are some screen shots of the panel and a alert dashboard. I am hoping to get some feed back on the UI design of the plugin and dashboard.
