I have never seen someone love a decorator more than you lol

I think this is pretty cool

One thing, I'm not sure how I feel about the ChangeFlag class

It seems like a lot of scaffolding just to indicate that the user has interacted with the imgui window...unless I am missing something

It's useful when you have a lot of UI elements that could have changed and you want to know if any of them have changed. It's cumbersome to write:

changed1, val1 = imgui.slider(...)
changed2, val2 = imgui.slider(...)
...
changed_n, valn = imgui.slider(...)

if any([changed1, changed2, ... change_d]):
  # recompute

# could also do
if changed1 | changed2 | ... changed_n:
  # recompute

Basically the following is invalid python syntax otherwise I would just use the or operator | with tuple unpacking:

changed |, val1 = imgui.slider(...)
changed |, val2 = imgui.slider(...)
...
changed |, val_n = imgui.slider(...)

This is valid without tuple unpacking:

changed = func()
changed |= func2()

Failures are due to an imgui update
