Here is list of features in the current build:

Edit Club attributes

Edit National team attributes

View Match attributes

Dynamic Lists for Clubs to show Teams and players/staff in the teams

Dynamic Lists for Bonus & Clauses in Contracts

Dynamic Lists for Relationships

Helper Scripts that either run immediately or periodically to:

Set Happiness, Fitness Condition/Sharpness, Training Happiness for all squad members of a Club

Set Favourability to Max for all members of a club

Set Fitness Condition/Sharpness for all squad at the National team (if you are coaching one)

Set budgets to high number periodically to allow free spending for recruiting

Set contract dates to current day (or back to join date) to help stop offers. (Better to add high value "Minimum Release Fee" to stop offers but both can be used)

Prevent Player or Staff Attributes from decreasing during monthly updates

A lot of values seem to be cosmetic and dont impact the game so dont expect everything shown to impact the game.
