First of all, thanks for a great mod!
It would be perfect if there would be an option to control/convert/switch between normal loader i.e. AAI/Deadlocks's one with 5 or more filters without lane splitting and one with only 2 filters and lane splitting enabled.
I'm using ones with more filters to limit what gets unloaded at the multi-item requester stations. I.e. in Pyanodon's game I have huge warehouse (~700 stacks) at the stations and loaders at that station have filters set to the items this station wants to prevent accidental train/manual train unloading and belt/warehouse contamination.
For me personally even an option to have an instant hand-craft recipes converting between normal and lane-filtering ones, and back would be sufficient.
I hate using splitters/two loaders to put two different items to separate lanes on a single belt so having any of such options would be a godsend.
