Not sure if this is intended to be a feature, but whenever you open a save, go to the front page (by clicking the button in the bottom left, and close TPT by clicking the X (in the top right), the original save appears instead of TPT exiting.
Steps to Reproduce:
1. Open TPT.
2. Click on the save browser button in the bottom left corner.
3. Click on the X in the top right (this is on Windows 10).
4. The save browser closes, and you are left with the blank screen you see when TPT opens.
Note how the TPT icon in the taskbar does not show 2 open windows.
This is happening on version 95.0.345 on Windows 10.
