I am Jaime Villate, a Physics Associate Professor at the Engineering School of the University of Porto, Portugal. I've maintained xmaxima, the Tcl/Tk interface to [Maxima] since 2006. However, I'm still a beginner Tcl/Tk programmer; I would like to hear any suggestions you have for improving that package. ---- '''[arjen] - 2024-04-01 09:17:09''' I was not aware of the Tcl/Tk interface to Maxima, I tried it and I find it more pleasant than the wxWidgets one I used before. (Though, I admit, I do not use it enough to really comment on the GUI :)) Are there any specific aspects that you would like to discuss? ---- '''[arjen] - 2024-04-03 07:15:39''' Can I post some questions here about Maxima? One is: quit() does not stop the GUI and after that I get error messages about channels that are not found. I realised that this was the problem after some experimenting ;).---- Yes, you can post questions about Maxima here. Regarding quit(), what operating system are you using?
