One of the key features of Merge Controller for GitHub is the ability to control merges by title and branch. For example, users can specify that pull requests with the title containing "[WIP]" or "[wip]" should not be merged into the master branch.

It empowers users to enforce specific rules and maintain the integrity of their codebase. This add-on is a valuable tool for developers and teams working on collaborative projects.
