Add grid system to shape tool
It would be really helpful for engineers and engineers to be if the ends of the lines would "lock" onto the corners of each square on squared paper.
That would make it a lot easier and faster to draw vectors, circuits, functions...
But only as an option that can be turned on or off easily like the lasso tool for selecting images or handwriting..., otherwise it would get very annoying.
Ability to create a grid for graphs would a great addition!
That is an excellent suggestion. Not just for engineers (I am one) but for people doing other functions from sales (like me) to students or other business uses.

It could be an extension to the shape-tool, like being able to choose the colour; or add the ruler that apple uses in its own notes app plus a grid system.

Agreed - and the most important thing when straightening lines is that the start and end points need to snap to where I draw them, instead of being moved by the straightening algorithm.
Oh, and not just the corners, the lines should also lock onto the grid.
