Theme editor

What it does: customize how the app looks — colors and accent — so it's comfortable for your eyes and your setup. Separately, View ▸ Text size scales the whole UI (Normal, Large, Extra large, Huge, Maximum) for readability. Your choice is remembered.

Safe to run: yes. It only changes appearance, nothing on the network.

Reading results: nothing to read. Custom themes are saved with your work and are included in Back up & restore, so your look comes across to a new machine.
