    Just a heads up: PySimpleGUI 5 isn't open source any more [0], and the official GitHub repo was replaced with a stub [1]. From the blog post, it sounds like the people behind it will probably remove the FOSS version from PyPI soon.

    It's possible the community will fork it with a version of PySimpleGUI 4 that's still kicking around, but I haven't seen one yet.

    Their old CONTRIBUTING file <https://github.com/PySimpleGUI/PySimpleGUI/blob/1fa911cafee6...> said:

    > Pull requests are not being accepted for the project. This includes sending code changes via other means than "pull requests". Plainly put, code you send will not be used.

    > I don't mean to be ugly. This isn't personal. Heck, I don't know "you",the reader personally. It's not about ego. It's complicated. The result is that it allows me to dedicate my life to this project. It's what's required, for whatever reason, for me to do this. That's the best explanation I have. I love and respect the users of this work.

    It's obvious in hindsight that those reasons were a bald-faced lie, and the real reason was exactly that he could legally do this rug pull.

    > 2023 is going to be the "Make or Break" year. I ultimately need to determine if the project is going to continue. To date, it's nowhere near sustainable. The income doesn't cover the cost of the project, meaning that it's not only unable to allow me to pay for my cost of living, but I continue to rack up debt, borrowing money, to keep the project functional.

    > This isn't new information if you've followed the over 1,200 announcements I've made since Sept 2018. The data is available should you wish to look at the GitHub Sponsorships and do the simple math required to calculate income from Udemy. It would be great for the project to keep going. I'm hopeful, but more than hope's required to keep the project going.

    So if you like this project and want to see it around in the future, please support it.

    The psutil package makes getting a list of running programs not very difficult. There's an example demo program that polls once a second and displays the top process using CPU time. You could use it as a starting point perhaps.

    How does it compare with remi? https://github.com/rawpython/remi

    Looking at the examples, for quick UIs, REMI seems simpler. And PySimpleGUI (https://github.com/PySimpleGUI/PySimpleGUI) offers REMI as a backend to deploy on web too (PySimpleGUI is pretty simple to learn).
