I'd like to propose that support be added for linear arrays when copying, similar to how it's done in Sketchup (https://tinyurl.com/y9ye5r9a):

When copying an object by holding down the ctrl key, after releasing the mouse, typing in "x3" will result in 3 copies. Likewise, typing in "/3" will repeat the copy but in 1/3 increments. This would be great for rotations and scaling as well.
