**Feature summary** (what you would like to be able to do and where):
Instead of making me manually write a signature at https://en.wikipedia.org/wiki/MediaWiki:BlockedExternalDomains.json / https://en.wikipedia.org/wiki/Special:BlockedExternalDomains , please automatically log the addition's time and username in separate fields.
**Use case(s)** (list the steps that you performed to discover that problem, and describe the actual underlying problem which you want to solve. Do not describe only a solution):
The list may become searchable later, but its edit history is stored separately. It may be easy to find an entry even if the list grows to a million entries, but it won't be easy to find out who performed the addition. This is why a "Notes" field exists, which could else just be a part of the revision history in form of an edit summary.
**Benefits** (why should this be implemented?):
- Less tedious process for creating a comprehensive log
- Standardization instead of a custom workaround
- The feature is new and improving it will probably be easier now than later.
