I have been having a hard time with creating my DP3T slide switch, getting so precise is important to make sure parts fit the way they should. I have the correct general shape and pins on the pcb view, but I need to change them. Is there a way to change the over all size of entire switch without going back to the schematic? In the schematic view, I have snap down to .1 mm, and then it becomes hard to get things exactly where they need to be.
Why can't the EasyEDA people expand their library of parts, as it can only lead to less problems for people who are not experts as using all the tools. The demo they do is simplistic, and never addresses the more complicated process of making something that matches an engineering drawing. Just placing pads on a page and drawing a box around it is child's play. Making a switch from a drawing that is exact, is much more difficult.
Brand new interactions and interfaces. 
Easy to use and quick to get started.

What?
Why do you need such a a tiny snap dimension?
The dimensions of the physical device only determine the dimensions of the PCB footprint. They have absolutely nothing to do with the schematic symbol.
For the schematic symbol you only have to make sure that the pins are correctly spaced to be on the 10 grid so that when you place the symbol in a schematic, the wires in the schematic snap exactly to the symbol pins.
You also need to add an outline and make sure there's enough room inside it for the pin names to not overlap or be cluttered but that is easily done.
