Simple Comment Editing version 2.3.6 has been released. It provides a hook that could (when overwritten) provide logged in users the ability to edit their comments indefinitely.
Simple Comment Editing Options has the option baked in, so if you want unlimited editing for your logged in users, I highly suggest purchasing a license.
Current Version: 2.9.5
