ModmailAssistant is a Devvit app that provides a few useful Modmail-related tools. Each of these tools come with some configuration options and can be enabled or disabled individually to your liking.
Auto-Highlighter
Automatically highlight new modmail conversations from the admins or specific users.
Auto-Archiver
Automatically archive modmail conversations after a certain amount of time has passed from the last reply.
Modmail Mentions
This brings username mentions to modmail conversations. Have you ever wanted to ask another mod a question in modmail? Now you can get their attention by /u/-mentioning them, which will send them a private message with a link to the conversation.
This section summarizes the changes made for each published version of the app, unpublished versions are not listed, but you can always view the full changes to the code on GitHub.
Added an option to ignore modmail /u/-mentions if they are inside a quote block. Enabled by default.
Fixed an issue where manually running the archiver would never work due to an incorrect permission check.
