Overview of all end dates from certificates

It would be really helpful to have an overview of all end dates from certificates from apps that you have access to. This will help with being in time when having to replace certificates.

Requirements of the certificate overview would be;

• There is an overview that shows the following;
  • The name of the application
  • The subject of the certificate
  • The end date of the certificate
• A notification will be shared X days before the certificate expires. X will be customisable by the user. 
   

Some nice to have additions would be;

• Option to add all end dates to your external calendar.
