"Lock Aspect Ratio" enabled by default, or enabled by shortcut
Currently, the "Lock Aspect Ratio" box is unchecked by default. But usually when moving or resizing shapes, it's very important to keep the aspect ratio locked. It would be great to have this enabled by default, or be able to temporarily engage it with a shortcut (Like holding shift as with Illustrator/Photoshop/etc).

Yes holding shift would be nice :)
