After following the simple example documentation, the plugin opens successfully, but the Space listing option in the plugin causes an error. There are a few other bugs as well. The Call Tree option hangs forever after the window pops up (the console is full of errors). The Access Map option has an error the first time, then opens but the graphics are all squished and generally unusable.
I'm on Ubuntu 24.04.
