Dope sheet - handy, time and energy saving tool

After reading about the huge benefits of dopesheet in The

Fundamentals of Animation I decided to make well...something similar. Because, since it it the first animation I think my head needs some help.
Dope sheets help to plan actions, their timing, camera movements and the synchronization of soundtrack in the most organized way.
Since our task is to produce only one-layered animation, with no backgrounds or to many element interacting the dope sheet is also less complicated.
My biggest hopes here are that it will help a sometimes scatterbrain me not to overcrowd my head by planning the animation in advance.
