Single use synergy tracker? Alert when should use again.

[Jhenox]

I started writing this with only necrotic/mystic/energy orbs in mind but I assume this can apply to a number of single-use skills (ones where only one can be active at a time) that can be synergized by other players. Is there maybe an addon that could alert me that my single use shards, orbs, etc has either timed out or been synergized so I know to fire another one? This came to mind when I was using orbs in a trial recently. Other players were using orbs too and it was hard to track visually. I was either not using orbs as often as I could or wasting magicka etc by using them too often. Any ideas are welcome. Thank you.
