Thanks for your reply and all the great work, duncan!
To illustrate my problem with Content Areas and my template, i post a code-snippet:
<a href="https://www.example.com"><img src="https://www.example.com/test.jpg" width="250" class="flexibleImage" style="max-width:600px;" /></a>
I need to make the href of the link, and the picture editable, and keep the users from editing the styles.
The only solution that is possible so far, is having a “textarea” and fill it with a dummy-img, where the picture needs to be replaced in ckeditor without breaking the styles.
Of Course this problem could be solved with adding a link field to the “image”-content area.
The second described scenario is a more global issue:
Its great that there are data-repeatable and data-hideable attributes, but what would change the whole game a lot, would be, if there is another attribute called data-block (or whatever). My whole template is organised in module-rows and it would be amazing, if you could establish a mechanism like in data-repeatable, where you can change the order of the provided blocks, duplicate blocks or hide a block like in data-hideable.
This would give the whole project more versatility.
And basically thats why I kind of envied Mailtrain for mosaico-integration. Because this drag-n-drop-interface is exactly what solves this issue.
