Can I use pon completely plain, without images and hints?

Yes. Under „Appearance“ there are three levels — on the home screen at the top right via „⋯“ → „Appearance“, or in Settings:

• Standard — with header image and greeting, the way pon ships.
• Plain — without the background images throughout the app; the lists start right at the top. Greeting and suggestion cards stay.
• Minimal — only your lists, without greeting and without suggestion cards.

Important: only display disappears, no function. Even in „Minimal“, pon still sorts by your route through the store, groups by store, reminds you in the right place and keeps learning as usual — you simply no longer see the hints on the home screen.

The setting applies to all lists and can be changed back at any time.
