tkterm VS CustomTkinter

I am working on something similar. I encourage you to take a look at https://github.com/axs5489/tkterm You want the tkterm.py and tksetup.py files. Its far from complete, but I figure I'd save you some time. Serial uses a menu system to pop-up various settings windows, returning them to the main window. I wanted the ability to pop up multiple instances of Serial and have them not interfere with each other (closing the first one used to close all). I fixed that by instantiating a master windowing class (minimized via the withdraw command), automatically instantiating a Serial object and having the ability to add/remove them. My current problem is getting the master window to close when its run out of child windows.

I like CustomTkinter. A UI library based on Tkinter, so you can also use Tkinter along with it.

All tkinter widgets with exceptio of Canvas are currently supported and ttk themed widgets used whenever possible. I plan to add support CustomTkinter eventually.

both custom tkinter and pyqt5 have somewhat "modern" looks.

If you go for tkinter, I recommend you use CustomTkinter instead. It looks much nicer with no extra effort

New GUI based on the splendid work of customtkinter: it is now possible to select files via a "Select files" button instead of the Drag&Drop function that presented several problems this new library allows for much more organized and optimized code the new interface is fully resizable and so adaptable to any screen the new interface also allows more space to add new widgets (in the future) to customize the upscale operations

Well, as I mentioned, customtkinter makes that fairly easy.

In last project I was used customTkinter.
