silly question i'm sure but do the 90 degree inserters work on 9.4 yet? and are there any half length and long half length inserters in here as well??

Also would a 90 degree half inserter be viable?

Is there a mod that means inserters will load a full stack in to a machine. or more specifically so they will load a machine up to a full stack. or would some one be able to make such a mod?
