I enjoyed FS '11 and still go back to it every now and again. I've never left the farms I started in it.
The first one I'm looking for is the hired workers one that lets you create a convoy to get all of your equipment from one field to the other in a single trip.
I think this one is the 'Follow Me' mod. It's available on FS-UK here
And the second is the precision laser one.
I believe this one is the 'alignment aid' mod. It's also available on FS-UK here
Hope this helps, and have fun!
