Another simple Desktop Widget using PySimpleGUI
A Counter Widget... X out of Y
Maybe you're counting the number of classes left in a course you're
working your way through, or the number of pokemons left to capture.
Whatever it is, sometimes knowing your progress helps. This widget shows
you the current count and the total along with your % complete via a gauge.
(Again, thank you to Jason for the gauge!)
