Here's an approach that first makes the data longer, then splits out traits from unit/method, then spreads those.

I suspect that [] as second argument in useEffect is the troublemaker. It causes the useEffect to be called only once with default props and stats. Try removing it:

You send value from global variable transformEnabled to function but for string/int/float/boolean Python doesn't keep reference to original variable but it copies values to new variable.

You could use global transformEnabled in function and change directly transformEnabled = True to assign value to global variable. But your complex is too code for this simple method.

In your code it is better to keep values in global dictionary and send strings "transform", "selection", "paint" and use them to access data in this global dictionary.

It is big change in code but you need it. Eventually you could try to use classes to create widget which keep buttons and values for one type of functions. You could also use Frame to group buttons and show/hide this frame.

I changed other things in code - based on PEP 8 -- Style Guide for Python Code

Looks like the issue is with setting the src - specifically the .attr() method from Jquery. It is a function to execute, not set a value to.
