Where's the battle calculator gone?

There used to be one in the game interface, and the codex describes it as well, but I can’t see it

I still have Michael Murphy’s android app, but it would be nice to have one in game again

Should be on the interface panel for a given star. Look for that series of parrallel lines at the top right corner. Hard for me to describe it.

sorry its a bit hidden.

Got it, thanks!
