## Additional notability info

I can't really do it justice as I'm not a Chess player nor am I up on the online world of Chess which this program seems to interface with.

There are a number of different color schemes. A lot of work went into the user interface.

It is super-lightweight and based on PySimpleGUI. It's remarkable that the entire program is in a single file that's large for a single file, but tiny for the entire program. The file is 3,500 lines long of which 2500 lines are actual code.


Review the linked Python Easy Chess GUI repository and the qualification checklist first. Confirm the project details and criteria, then add its name, description, and links to the appropriate application list; done when the entry is present and accurate.
