# ---------------------------------------------------------------
# LEVEL UP! Try one (or more) of these upgrades:
# 1. Add a Slider to choose the tip percentage instead of a fixed 15%.
# 2. Add a button that clears both text boxes.
# 3. Change the colors, fonts, or window size to make your own theme.
# 4. Add a second window (App) that pops up with a "thank you" message.
# 5. Turn this into a different app entirely: a BMI calculator, a
#    temperature converter (C to F), or a simple quiz with score.
# 6. Ask your AI tool: "How do I add an image or icon to my guizero app?"
