[Todo List] Details -> Notepad

[talison-cardoso]

The notepad doesn't work well, it has a fixed height and no scrolling, that is, adding something with more than 5 lines is unfeasible.

and the mouse is only displayed if there is some text on the line, that is, a blank line with no information on where the mouse should be
