The idea is more in-depth editor and system to the plumes. I get to idea that being limited by what you have inspires creativity in the player, but I'm not a good programmer, so I'm asking someone else for what I think would be cool.
What I think would be cool would be a built-in editor to the game like ember, where you have more options to shape the mesh of the plumes, and include multiple effects in the plume. To create more pretty shock folds and diamonds, just like the waterfall mod in KSP. I don't know how difficult putting a system like waterfall in this game would be, but if Linx could put Parallax scattering in this game, I'm sure it's possible.
