At our company we found the need for customizable scaffolding.
While it is possible to have scaffolded screens automatically use a style we found it would be handy if we could customize the scaffolding to automatically put actions like delete with our company style pictogram and change the edit into an edit popup with a special column for this edit and delete. etc. etc.
Now we have to manually put a webblock inside every new screen we create and alter it with the correct names/ids.
Really hope this feature will be in a future version!
