EasyEDA suggestion 2 | adding scroll bar to the work station

Components

The component here I want to suggest is to add a scroll bar in work station of EasyEDA.

Proposal

When working on a schematic capturing, There are some diagram that contains many components and make the diagram very wide. For us to focus on a single component, we need to zoom up the diagram to see clearer. What will happen when we zoom is some parts of diagram will not be seen. We need to scroll up-down or left-right to see the uncovered part.

For the current situation of EasyEDA, scrolling the work station can be done by using the arrow keys. Well, some user like me found it inconvenient.

What I want to propose here is to maximize the function of the mouse. We can add a scroll bar that can be used by the mouse.

Mockups / Examples

For example, this is the current diagram. And i want to zoom out that area.

This is what it look like when we add the scroll bar.

Benefits

It will be beneficiary to all EasyEDA users to maximize the function of mouse. Not only be used for zooming in and zooming out, but, also for scrolling the work station. Scrolling with the mouse is common to most software. It will be very useful to users who are used to use mouse to scroll work station as what they did in other software.
