I only need the interface of the mod, with the indicators of evolution. Is there any way to get it? Just, I play with Rampant, and it adds many kinds of enemies, and as a consequence, it takes up VERY LARGE amounts of RAM. And by adding Schall Endgame Evolution, for the sake of the interface, I'm adding more new enemies on top, which are also duplicated under Rampant and I'm consuming several times more RAM and VRAM. (8gb VRAM, 16gb RAM and 32gb memory swap file).

So if you could release a GUI-only version or tell me how to extract this and do it myself, I would be incredibly grateful.

Yes, the two parts of this mod (GUI and high tier aliens) are both optional, which can be toggled independently.

Simply set in mod setting "Highest alien tier" to 4 (as mentioned in option tooltip) should fulfill what you need.
