Please add this feature to XCS. Most graphics programs have this and it makes aligning objects so much easier.

Nine radio buttons can be used to define nine different reference points for object coordinates, facilitating precise alignment within a space. These points are typically arranged in a 3x3 grid, representing the top-left, top-center, top-right, middle-left, center, middle-right, bottom-left, bottom-center, and bottom-right corners of the object. By selecting a specific radio button, the object's coordinates are measured relative to that point, allowing for accurate placement and alignment with other objects or the page boundaries. You can even type in the precise coordinate to align the object based on which radio button is chosen for that obect.

Here's a breakdown of how these nine radio buttons can be used: 

For example, to accurately align a square in the top-left corner of an 8 1/2" x 11" page, you would select the top-left radio button, input 0" for both X and Y coordinates, and the square would move to that precise corner. If you choose the center radio button, it will calculate the center point of the square and align based on that.
