Selecting segments with eMarker difficult

[kolabria]

With the current sensor and electronic pen the accuracy is poor and it is difficult to select line segments and click on the X to delete.

Accuracy is related to location of pen on screen and the angle of the pen.

Change from clicking on object to select to dragging selection square around. This will hid issue.
Make delete icon bigger.
