Hi Dave,

Is it possible to have a mod menu/gui to switch the position of blueprint anchoring?
Gui I mean.. like this:
Center is what it is now. But sometimes it would be much easier to calculate from the corners (eg.: bottom left 1st grid, or if built from right to left, then bottom right corner..) This is especially the case when you try to use even numbers (11,13 etc. )

Like this (just turn it 45° sideways) (https://previews.123rf.com/images/vectora/vectora1410/vectora141000024/32304116-button-with-arrows-in-four-direction-remote-controller.jpg)

Edit the blueprint.
Turn on snap to grid.
Select absolute.
Set width and height to 1 (or 2 if you have rails).

This will anchor the blueprint in the top left.

To move the anchor around, edit the first set of x,y values. You can see where it is by the flag in the blueprint.
