I feel weird making this request considering that you're the author for both mods, but any chance this could support the a heated version of the long-handed fast inserters from More Long Inserters? I don't see it in my playthrough, and I don't think I'm missing any tech (I have up to the heated stack inserter version now)

Hm, I always wondered if it was necessary, since combining both effects might bloat the list of inserters (a long for every inserter, a heat for every inserter, and then a long-heat for every inserter), but I can look into it. It might be easier to do this from the More Long Inserters side

Personally, I don’t mind. I mean, as a user, if you installed the “More Long Inserters” mod and were upset that there were too many inserters to choose from, that mod probably isn’t for you 😅

Implemented with v1.2.2 of this mod, and v5.1.7 of More Long Inserters (had to make some minor changes to make next_upgrade target work in all situations).

Heat makes the base heat inserters, then More Long makes the long heat inserters based on those, toggleable via setting that is disabled by default. Technology unlocks seem to be working properly as well (copied into the same tech as the normal heat variant)
