Thanks for consideration, i do not think that current ui separator as field is that bad a solution as it is part of the scheme and is intuitive enough. At least for me.
Tabs seem like a complex feature. Also, I’m not sure if it actually brings that much benefit for scheme design part as this is what is currently actually hard to manage.
Quick research from other cms:
Hygraph (graphcms) seem to not have any separators.
Strapi also do not have “collapsible” block during scheme defining. But they use concept of “Component” which is basically “wrap” for few fields (component in squidex are their “blocks”).
Anyway, their separation of that “ui separator” or component how they call it seems to be a better solution. Same scheme will be clear in squidex.
note: Icon in colorful box seems like nice improvement too.
it is similar to what squidex have currently as it basically uses field.
It looks like they do not have anything as separator
