Currently when UV unwrapping using cube, cylinder, sphere.
The object origin is used for UV unwrapping uses the objects origin as the center for unwrapping.

However you may want to specify a different origin (instead of moving the selection first).

Hi, to get into blender development i tried to solve this as a first practice.
Here is my approach:
https://developer.blender.org/P399
Two things I was wondering about:

I had to alter the "ED_uvedit_unwrap_cube_project" to take the varying center into account.
The function is referenced in "paint_image_proj.c". It now takes an additional parameter (offset) which can be null.
I hope that is not a problem even though it is outside of the task's scope.
I'm not very happy about how the center is set. Currently you have the option to "use cursor as center" which only updates when set.
Is there a better way? Maybe have a button to "set center to cursor" which sets the center coordinates to the cursor. (Is it possible to have buttons in the operator settings?)

I hope this helps adding this functionality!
I tried following the coding Guidelines and hope my code is not to ugly ;)
I am happy about any tips to create better code or how the development pipeline works.

best regards,
Sebastian Witt

Is this still being worked on? I'd like to claim this task otherwise.

Well the code i posted basically works, maybe I should create a revision for it. Apart from the questions it should work.
But since Campbell Barton left Blender as far as I know and this is not very important this is on ice.
I mean you can give it a shot if you want to try but its basically done.

Ok. I was a bit confused as the revisions you made hadn't been added to the most recent Blender source code. I'm guessing no-one else checks on these quick hacks but Campbell Barton? Is it still worth it to work on any of the "hacks" posted by Campbell then?
