I’m starting using kivy library for application softwares and I would like to create a management software. For a better explanation I would like to write a software with grafical parts, to insert workers, their tasks, deadlines, etc…I would like create my self to create a customized software. I would like to ask if someone has a tutorial or examples of management software in python. I would like implement it on by my self.
