Ability to see what Email Templates are and are not used

[ErikaSF123]

Is your feature request related to a problem? Please describe.
Email Templates are difficult to ID what is and is not used in the basic UI. There are some SOQL you can, but it is a challenge when you org is older and tons to go through.

Describe the solution you'd like
A UI that ID if an email template is referenced anywhere (like an alert)
To be able to see what object is it used for w/o having to open it
Last time is was used (not sure this is 100% tracked though)
-Between Object used and if referenced in Alerts, this would give admins a solid start.

Describe alternatives you've considered
Export the Email Template to Excel via Workbench and then click through one by one.
I have not found any app or OOB way that supports this.
