This is a simple Soul Shard management tool with one purpose: To remove all Soul Shards which are not currently in a Soul Bag. It was created to be a quick and easy way to get rid of excess soul shards.
More features may be forthcoming if there is any interest.
The mod creates a small round button near the mini-map. Mousing over the button will show a tooltip which shows the current version, as well as the two possible options:
Left Click: Purge Soul Shards from non-soul bags
Right Click (and drag): Move the icon
