First of all, thanks for the various UI bug report/complaints, I'll address them in the full game! especially the one about biomass triggering collectors even if biomass storage is full, I've actually been trying to find the cause of the bug reported by other players!
And finally, noted on the QOL suggestions, specifically #1 and #3!
I'll add #4 to my backlog of things to address! as for #2 (adding a pause) I can't say I can address that, as the game is programmed to be unpausable (the game even simulates runtime when you have the game closed after you've unlocked the relevant prestige abilities).
Again, thanks for the in-depth comment!
