I didn't see any posts here about sharing custom templates. I took a look at /r/enpass as well, but that subreddit seems to be dead.
What I wanted to do was start a thread where we can share custom templates we've created, just in case others may find it useful. I first started looking for a template to keep track of SSL Certificate info, & found nothing. To start, this is what I have for SSL Certificates, but plan on improving it.
