While zoomnig in by a specific part, the editor self center's itself in the middle of the page, forcing to manually move to the place of interest (by the part the work is done), with is very annoying and makes the work more difficult, aspecially in bigger circuts (aspecially, when a big zoom is needed)
@mcgiwer,
Please post an animated gif or sufficient screenshots to illustrate your point.
@mcgiwer, the zoom in EasyEDA focuses on whereever your mouse cursor is.
I can say that this becomes a problem when using a laptop touchpad as you can't 'steer' where it will zoom in. Adding a function like Photoshop where holding the spacebar temporarily changes the mouse to a pan mode would solve this.
Brand new interactions and interfaces. 
Easy to use and quick to get started. 
don't understand what is your problem
