Development #36

Favor instant visual changes

Animations, whether created with CSS or performed by JavaScript, generate lots of repaint/reflow. It is thus better to use instant rather than animated changes in order to use less CPU resources.

Development #53

Avoid rewriting getter/setter natives

Most object languages suggest standard getters and setters that the developer does not need to write.
Overloading them can increase the run and compilation time for these methods, which are generally better optimized by the language than the developer.
Consequently, use the standard getters and setters whenever possible, and implement methods that suit the purpose. This method has the added benefit of making maintenance easier for other developers, who will be more used to the behavior of standard getters/setters than those specifically implemented for the project.
