Do not use presets for new projects. Presets will be deprecated in future versions of Kirby.
If presets are to be deprecated, what should we use in their place? For example how should one show an overview of subpages in the panel, like described here? Pages | Kirby CMS
Because people keep running into issues as soon as they want to extend them. Then more often than not, you have to use sections anyway, so better start with sections right from the beginning. It’s also more confusing if there are different ways to do the same
I think we will first deprecate them, probably in 3.7, and then remove them in 3.8. The warning in the guide is there so that people starting new projects won’t start them using those presets.
