Is is possible to design a side bar for neuron editing mode? Like the one of tereFly. The bar will pop up when user enter editing mode and features a list of icons corresponds to neuron editing.

So instead of right click in the 3D viewer, the user can directly click the buttons in the bar to do different operations (like the tool bar of photoshop).

The button that may need:
save - 1-click save function
cursor - normal mode
pen - 1-right stroke draw a curve
eraser - 1-right stroke delete
scissor - 1-right stroke break
door - finish editing and quit the mode

This will also be helpful if someone is going to use Vaa3D on touch screen to edit neuron.
