I'm a usability guy, so my first concern with any feature or application is consistency, I guess all you guys and galls know that rule of usability, its the most important one.
So, when in one day a couple of questions came up on how to scale a KPresenter object but keep the aspect ratio of the object, and how to disable the grid while scaling, well, I got thinking and I started looking into what all the KOffice applications did.
In short, each one invented its own way of doing things. Which, as my introduction states, is not good usability. Duh!
