m1pro is a Chrome add-on developed by Alexey Dymov. It is a helpful extension for the Monopoly One game, providing various enhancements to the user interface and user experience.

The add-on improves the game page by displaying the remaining chances to land on the "Chance" field in an additional block on the right side. It also highlights fields when a player moves, allowing for easy selection of available options. Additionally, it shows live updates of other players' contracts and provides a list of all contracts during the game.

m1pro also enhances gameplay by displaying the outcome of landing on the "Chance" field, always showing the player's actions menu as icons to the left of their token, and ensuring the player's color is always red regardless of position. In team games, the ally's color is displayed as green.

Furthermore, the add-on provides information such as player ratings, previous MFP bans, gender, and friendship status. It also displays the credit status, total player value, and the cost of properties that can be mortgaged.

Other improvements include displaying the team's available assets in 2v2 mode, overall game statistics, the number of laps completed, and income details for each player.

m1pro also enhances various other pages by utilizing the available space, fixing the top menu to the left side of the page, and displaying the current number of registered items in the market menu. It offers options to hide rarely used blocks in the game search page and allows players to blacklist others to hide their messages in the main chat.

Overall, m1pro is a free and valuable add-on for players of Monopoly One, providing a range of UI/UX enhancements to improve the gaming experience.
