I love this mod, and it's very useful, but I have a suggestion -
When I'm building a loader / unloader (normally for trains) I sometimes want to reverse the inserter load / unload ends. For normal inserters that's not too bad, but when using something like Bob's Adjustable Inserters that's a rather large grid - and reversing the load / unload "ends" can be somewhat annoying.
As a use case - I have a train unloader, for a six car train, each section has 4x inserters (in a 2x2) on either side of a 2x2 chest, there are then a further 12x inserters pointing at a 6x6 chest - with the row of them also having 8x inserters between (and overlapping) each large chest so everything goes to one end (where it then gets taken further away) - I want to make a train loader from the same base pattern (then add some logic for rough balancing) - the speed is really good (unload a train in around five seconds - and I'd like something similar for loading)... Unfortunately that's a lot of manual editing (then copy/paste so it's not quite as bad as manually changing well over a hundred inserters manually), and just having a button that swaps the ends would be significantly nicer!
