Please include 'Price' as a plugin detail shown in the 'Show More' (details) pane for each Plugin of the Plugin Panel / Plugin Manager included with XD.

Specifically - 'Free', One-Time Price or Subscription.

This would save a lot of time in either researching a Plugin, assessing it's value or avoiding installing / using a Plugin that you wouldn't otherwise bother with if you knew, for example, it required a subscription.
