Features: New tools like square, circle, lines

[shimatai]

Please, add new drawing tools like square, circle, lines (vertical, horizontal, freestyle).
Some other drawing softwares allows you to hold Shift key to draw a perfect horizontal ou vertical line.
It also would be nice if there's a button to take the screenshot and save it to clipboard.

It's there in windows as well as the app
