Java FX GUI to do list application for uni classes

Application progress:

1. Base of logic - all nodes for to do app
2. Display tasks on the screen
3. User controls
4. Code refactor
5. Better look of app

User can create new tasks, he can manage priority of them and make subtasks!
Task creation process and adding subtasks:

Managing tasks, subtasks: - removing subtasks, uncheck tasks, move whole tasks or just some single subtasks.

Code is a bit messy, but it was my first time doing GUI in JavaFX. It was pretty neat experience, but styling via css has a lot of weird rules, and most of classic web rules just doesnt work here, which was very annoying.

Built using Maven and JavaFX.
