The mod is great and the commands to migrate from an existing save are very impressive, but not too perfect.

1) The /fib command didn't work for me, possible due to a clash with the janky quality mod. I had 1 purple inserter in my inventory (basic quality) which didn't convert. This was easily bypassed by simply placing it on the ground and running the full command again.

2) My existing filter inserters set to whitelist all changed to blacklist. It's a pain to have to fix them all by flipping them back to whitelist.

1) mod wasn't supposed to change items in inventories, and I'm not sure if I actually want to do that
2) you ran full convert - it switches all existing usual inserters to blacklist, then replaces filter inserters with usual ones, saving their filter modes

Ah OK, I misread what the commands did. I should have used them the other way around and it would have been fine.
