Inserters can fish from the beginning of the game for me, so I don't know if the research for "Inserter Fishing Control" does anything?
The ore refining is really cool, but refining alien ore makes it go from one ore one plate 17.5 seconds, to one ore two plates 2+4.8 = 6.8 seconds, or 3.4 seconds per plate. Since the alien plate bullets are overpowered (just a little) I go from just getting enough bullets to manage (or dying) to having plenty of ammo on high settings. I may need to make my enemies even harder.
A third small issue, the keybind controlling stuff: control-A. It prevents me from walking left while holding control, such as when I'm trying to insert things into assemblers/furnaces. In the control options, I rebound it to control-z, and it kept that setting during a start-up change, which was a good thing for me, but idk if that's what you expect. I'm also not sure if rebinding mod keybinds was a feature added in .17, because a number of my mods added keybinds and they're all there, which I was surprised at. The keybinding probably doesn't need to be a start-up change, but since it can be changed in controls..... I don't know. Not sure if it's worth caring about.
