@bastianallgeier just a couple of observations from the UX point of view:
- the button to add a new page seems a bit unintuitive (01:34). The title tips are fine but having “Add” and “Add & Edit” as labels instead of the “Ok” and the pencil icon can help people to easily understand the actions to accomplish, on both desktop and mobile devices
- drag & drop files upload is an invisible feature (2:52). The risk is that many people will never notice this feature. The drop area should be limited to the files section of the panel adding a small informative text about this feature and/or an icon hinting a droppable area
- the visibile/invisible status option hides the order functionality (4:12). A separate option/dialog should make both the ordering action and its status immediately visible. At the same time an invisible page should reset the ordering status and vice-versa making this relation explicit
Finally, a question about security.
Can the CSFR protection used by the panel shared in some way with the front-end website? I’m referring in particular to the possibility of having some helpers to generate a token and validate “regular” and AJAX requests.
