New features:
1. When creating traces, hit would be interesting to allow snapping in the middle of pads, even if they're not on the grid; By [Martin](https://easyeda.com/project_user_martin_1.htm)
2. I have found Eagle's "precise" adjustment feature useful, ALT snap size = Snap size/2. When you press `ALT` key, the snap size will be overrided by half. By [Martin](https://easyeda.com/project_user_martin_1.htm)
3. press `ESC` key twice to enter select model, some users don't know double click right key to enter select model. suggeste by Bill via email.
4.Adding a supply Flag at the left EasyEDA lib, There are some newbies can't find a GND symbol. we will add some other symbols, such as earth soon.

5. Checking the Top right of every float toolbar, we remove the X close button, add a collapse button. Some guys close the float toolbar by msitake and can't find them again. If you really need to close them, please do them from config toolbar

6. Importing other EDA files will be faster.
Enjoy it and give us some feedback.
