Things that may need to be done to make transition smoother for people: -Being able to read old region file formats and import them seamlessly. -Re-adding transparency to the region drawing in Region Editor. There is some issue with doing this when the regions are drawn to a bitmap and the bitmap is drawn to the window. -Test for the text to speech module, pyttsx, and avoid importing if it is not available. Also disable the “Speech” option in audio feedback. -Check which operating system is being used and make appropriate substitution for module winsound.
