We would need to have a Reserve button in Setting Dialogs.
In the Settings of Elements, Viewpoints, Views, Layouts, Master Layouts, Subsets, and very importantly the Book.
You can spend quite a lot of time in these dialogs to be setting everything diligently then realizing the OK button is greyed out as you forgot to Reserve beforehand.
Only the first one of the above list (Elements) is affected by the optional Work Environment Settings to make reservation of selected Elements automatic, however that setting is not something we usually want people in our office to use as many of them want to make sure they are just checking things and not amending them accidentially. But even more importantly this WE option isn't even a solution for the majority of my list above.
A Reserve button would be much more safe, useful, and consistent with the settings of the Attributes.
