Very useful to have tools for 2d alignment: linear, circle, rectangle and matrix...
but you forgot to add linear vertical/horizontal because the tool works only in one direction.
Now the steps to follow to rotate a strip of fixtures are: align them horizontally, then link, then rotate, then unlink.
Too much steps!!!
it's easier to add vertical/horizontal alignment
please add free alignment tool, I draw a line and all fixtures will be aligned on this line
Also (much easier for you):
alignment with rotation: I can distribute the fixtures linearly and I have another control to rotate all the alignment
