What do you have in mind for the style and theme of the web page?
Open to suggestions given the wide audience. But I usually prefer clear/white backgrounds, with some blue or gray boxes.
The actual page containing the tasks list. The home page is going to be the actual tool where you can immediately start creating tasks and be prompted to save your work later on. You will also have a login button so you can load your previously saved work. I made a simple wireframe which has some key elements I want but you should feel totally free to come up with your own graphics, DISPOSITION of the elements, etc, always having UX and easy of use, learning curve, in mind -> https://wireframe.cc/tsAiMd
A thing to be noted is the hability to create nested subtasks, so I don't know if it is a good call to have in each task box a button (Create subtask) which then expands the task box to reveal a subtask input field which after pressing ENTER will create a nested subtask box. But I do want the hability to create from the main view nested subtasks.
I want the tasks to be drag'n'drop enabled to reorder them, and to switch from one STATUS to another.
