Create a simple layer specification using MapComplete studio with 'images' and a question. The actual _topic_ of the layer can be chosen by the participant
- [x] If the 'name' or 'description' of the layer are not given, it cannot be loaded as 'fake' theme. This needs a clear warning message
- [x] The explanation of the field `render` uses `&LBRACEkey&RBRACE` instead of `{key}`
- [x] The freeform textfield only takes a small part of the screen, should be made full-width
- [x] The 'render'-field should be moved in the 'freeform' section
- [x] A pending `Translated value:` is still shown in the UI (for debugging purposes) - should be removed
- [x] The 'textfield' of the 'Translated Value' should be hidden - especially as it contains JSON
- [x] If an external dataset is loaded, a 'read only' mode should be triggered causing the 'question' - part to be disabled
- [ ] snapToLayer-section under presets section is not immediately clear. The participant realized after a few seconds what it meant drawing on their extensive MC-experience, but a beginner would not be able to figure this out
