Add a smoothing bar to path creation so that smoothly curving paths can be more easily created

The current path tool is a raster tool allows the overall resizing and placement of a brushed path. Roads are not usually adjusted that way (moving the entire road or stretching it). More often you just need to adjust the placement of a small section or bend of a path. It would be more useful if the path tool was a vector tool, which creates editable points, connected by a Bézier curve. The curve could have an option for how tight vertices curves are drawn.

So I am an AutoCAD user and instructor. One of the things about being a drafter is everything is done with intent and precision. This means all the line work is exact and meaningful. That being said, we have a tool to use called Object Snaps (OSNAPS). This tool allows us to precisely and accurately connect line work. Could something like this be implemented? Say your building walls for a house interior, you have to zoom in and manually line up the walls, with the SNAP feature, you do not have to guess.

Sometimes it's hard to build large buildings piece by piece, and large circle-shaped buildings are specially tough.
