These are actually 2 related topics which are, or at least feel, to be time consuming.
First: It would be great if we could define default labels for attributes to be used on grids and inputs. In most cases the attribute name is just not the right UI label and in multilingual projects this is even worse. You spend a lot of time on putting in the same labels again and again or need to use some workarounds with the language operations to fill in labels and translations later on - wouldn't it be cool if that autogenerated page is 'really' ready to use, including multilingual labels?
Second: a similar problem occurrs with the standard buttons for 'Save', 'Cancel' ... - these always need to be translated or relabeled. Here we could also just store the standard labels per language to be used on these buttons.
