Colonizer

Appends semi-colons (or whatever you want!) at the end of the current line.

Get it here!

Its default key bindings are

ctrl+;: Append a semi-colon at the end of the line.
alt+;: Append a semi-colon and a line break at the end of the line.

Changing the appended character

In order to change the appended character, you can set the "colonizer.value" user or workspace setting.

Changing the key bindings

You can change the default key bindings by redefining the "extension.colonize" and "extension.colonizeAndBreakLine" commands.

Enjoy it, and contributions are welcome!
