In the context of working with some style and make learning easier and faster for the user, I find it’s a good thing the user interface is as homogeneous as possible.
It can sometimes happen ( now for me!!! ) that after having generated hundreds of applications you discover a new way to make the toolbar more ergonomic.
Now the solution is to manually edit each application with a great loss of time, while it would be nice that the default properties of the project such as the arrangement of buttons on the toolbar can be applied retroactively to applications already generated and not just for those new.
Thanks for your attention.
