Frontend editor in backend with PageTableExtended

[theo]

I know this sounds a little weird, but I'll show you what I mean.

I have now integrated Bootstrap 4.0.0 in the backend with PageTableExtended.
This works rather well. Here you see Bootstrap 4 cards in the PW backend:

 

To make some changes here, the editor can click on the edit icon and the pagetable / repeater opens.
(The editor can define to some degree the width of each card here. ;-) )

This is all working well.

Since I can edit the fields in the frontend directly (This is the frontend!)...

..I wonder if this would also be possible for the PageTableExtended in the backend.

Just clicking on the CKEditor to change some content quickly, without opening the pagetable modal window?

Has anyone already considered such a thing?
