Keep the program on top

Just like the one in the picture, a pin-like function could be added to prevent the countdown page from being hidden when I click on other windows

I have forked this project and added functionality to keep the application window always on top. Of course, there's an option to toggle and revert to the default window behavior as well. Feel free to use this project if you like. Below is the link:https://github.com/linfeng521/Easy-Cat-Timer
