Nice plugin. Was able to get it working soon enough. Adding a callable and providing values for the arguments was easy. Recognizing the argument types makes it very easy to enter the values (int vs vec2, for example). Would be nice to show the function argument names in the inspector, if possible. One behaviour I noticed was if a function argument name changes, the callable gets reset with a "Function Missing", and the functions and arguments need to be entered again. Is that intentional, for eg, to avoid any mistakes, etc? Re-ordering the callable sequence is a useful feature. Neat work overall!
