Adopt new GUI toolkit

[arky]

Perhaps adopting a python native, GUI toolkit over like toga would ideal for providing similar look and feel across multiple platforms.

Tinkerer still is a viable option just not as flexible as it needs to be bundled across multiple platforms.

You are probably right. Tkinter might not be the best option, but I started working with it a few years back... Given the fact that everything works on Tkinter now, it will be a huge effort to rewrite the code to another GUI toolkit.
