```{page-status} stub
:summary: see page introduction for details (2026/03)
```

This page is **just a stub/draft** for now to list a few concerns and collect resulting features and aspects for later refinement.

Features:
 * storing/loading settings and configuration
 * storing/loading general application data
 * synchronizing between instances

Aspects to the development procedure:
 * persistency triggers the need to consider backwards compatibility (old files)
