GP feature request: Combine line and curve tools altogetger into a one toold + alt key hotkey to move only one curve handle

Hello guys. This is part 3 of my feature request for grease pencil. I am aware that grease pencil is more of a 3d than a 2D application but there is a big resemblance of its implementation to vector editing softwares. I believe adopting some of the basic tools that a vector editing software commonly uses would be a very significant addition to blender and could possibly be a game changer. This will male the work more easier and faster.

In the demo video, I would like to point out the specific basic tools in handling curves can be an essential tool for grease pencil.

1.) Pen tool == curve and line tool combined.

blender currently uses multiple tools. The curve and line tool are two different modes. Introducing the pen tool would make the ui much simpler and no need to switch constantly between line and curve tool.

2.) Affinity Designer has some types of node handles which includes the sharp, smooth and smart. Blender may find these helpful when dealing with curve/stroke nodes.

Thanks.
