HI
When you make technical drawings for engineering machines, most of the lines are straigt ones at 90° angles.(verticaly and horizontaly)
One thing I would like to see is the ability to have a additional Icon for straight lines, vertically and horizontaly.( icon single line --> restricted and non- restricted)
So that you do not have to puch al the time on the shift key.
... not an essential thing... just handy sometimes... and make life easier.
