The whole GUI of Nagstamon has been refactored. It became split into several files instead of being stuffed into one big file. This makes it easier to maintain and extend the code in the future.
To make sure it still works as expected, or even better, you are invited to test it. Get your copy of Nagstamon 3.17-20250821 at https://github.com/HenriWahl/Nagstamon/releases/tag/latest.
