Ability to do the following
- able to lock both blue and pink guide line (drag by accident when selecting an object)
- ability to lock layer or objects (drag wrong object by accident due to overlapping)
- want to hold down the shift key and click on an end point of a line already in either vertical, horizontal or 45 degree and extend said line. Right now if I want to extend a 45 degree line, it is not possible. I have to redraw the line longer.
- extend the tick marks in the ruler, for example 25, 35, 45 to be longer if possible (would be nice - but not important )
