I'd love to have some custom priorities. For example, I'm far overproducing Vulcanus science, but struggling on Fulgora science. It would be cool, if I could prioritize Fulgora science over Vulcanus science.
This gets crazy when modded science packs are at play too, which might spoil too or have other weird stuff going on (like research on multiple planets).
Other people might have different priorities. So I suggest having some kind of "advanced/custom" mode/section in the mod settings with a text field for every science. There, the player can enter their priority for the science. A byte of data should be more than enough to also cover modded science packs.
Say, you set Vulcanus science to priority 20, Fulgora science to prio 5, Gleba science to 1, yellow science to 15, purple science to 30.
This would then switch to yellow science (say, weapon damage) if yellow science is in stock, prioritized over vulcanus science.
