CustomTkinter VS TKinterModernThemes

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.

Matplotlib or Plotly will give you grafana style plots, the rest of what you want (Buttons, Entry Boxes, Labels) is all in Tkinter! If you don't like the look of tkinter, you can change it with this, this or this. (that last one is my favorite).

I'm trying to figure out how I can add these tabs - Files, Purpose - to a listbox but haven't found the right attribute to it https://github.com/RobertJN64/TKinterModernThemes/blob/master/TKinterModernThemes/images/azuredark.jpg

Did you look into tkinter modern themes?
