Choose a TreeNote theme that suits your environment and working hours. Switch the look of your outline instantly while every item and structure stays exactly the same.
Themes change the presentation of TreeNote, not your work. Your notes, structure, dates and checkboxes stay exactly where they are while the workspace adapts to your environment and preference.
One chord cycles the available looks, with no trip through settings and no reload.
The same choice, made deliberately, when you would rather pick than cycle.
Your chosen appearance applies without interrupting the outline — the cursor does not even move.
The best system is one you can return to. A comfortable workspace removes a small but constant source of friction, whether you are writing a book, studying for an exam or running a project all day.
Change the view in one step, then get back to the work that matters.
