I haven't drilled down into the implementation here, but classic Miniloaders allowed decoupling belt lanes so, for example, a different filter could be assigned to each, producing a belt with distinct items on its two lanes.

Given the direction 2.0 has taken with circuit networking, it might make sense to offer the option to distinguish red and green wires connected to the miniloader for purposes of independently assigning filter sets per lane.

Another non-default classic Miniloader option is to unlock inserter stack sizes. This has two benefits and one drawback. The benefits are that researching non-bulk inserter capacity upgrades reduces the cost in two resources: power usage and UPS. The drawback is that if stack size is unlocked (and the lanes are not split) a miniloader no longer behaves as a perfect lane balancer in circumstances where the multiple pickup of its individual inserters makes a difference. IIRC classic Miniloaders treated this as a save-level global option, but it might be advantageous to make this an entity-specific option.

I'm a big fan of these features, personally, though I never really could use the split-lane feature properly due to bugs — to wit, lane configurations were very likely to be unintentionally reversed across a save-load cycle, making this amazing feature lamentably impractical.

Are there any chances of supporting these features? (... and if so, does that chance require implementation assistance?)
