Ability to make a note added in a task more visible

Context: An employee of Ms. Mélissa Boucher of "cmmascouche" created a task in the wrong file.

She marked it "completed", and added a note mentioning the error.

She thinks the note is too small and could go unnoticed.

She would like to be able to make the note bigger and be able to change its colour to red to make it more visible.
