Mortal Reviewer Enhancer is a Chrome extension developed by kokeman that aims to enhance the usability of the popular Mahjong game viewer, Mortal. With this extension, users can enjoy additional features that make reviewing game plays more convenient and informative.

One of the key features of Mortal Reviewer Enhancer is the display of bad moves (moves with a π value less than 5) or discards for each turn. This allows players to easily identify mistakes or suboptimal moves made during the game. Additionally, the extension adds an update button to the viewer for each turn, ensuring that the viewer reflects the current state of the game at that specific turn.

The extension also enhances the metadata section of the viewer. By default, the metadata section is opened, providing quick access to important game information. Furthermore, the extension adds the bad move rate (number of bad moves with a π value less than 5 divided by the total number of moves) to the metadata, allowing players to analyze their gameplay more effectively.

In terms of layout, Mortal Reviewer Enhancer sets the default orientation to landscape, providing a wider view of the game board and improving the overall viewing experience.

With Mortal Reviewer Enhancer, players can enjoy a more convenient and informative experience when reviewing their Mahjong game plays on Mortal. This Chrome extension is available for free, making it accessible to all Mahjong enthusiasts.
