thank you for your feedback,
the module now is on its way for stabilisation, right now it is not finished and actually not ready for the actual release.

Currently, I am in progress of borrowing of geometry managers from tcl/tk, which is somewhat non-trivial, and am planning to finish with geometry managers in a week or two.

After that, will need to implement callbacks (also with tcl/tk like syntax) and then investigate about memory leaks.
