I made some concepts regarding this a while ago so I’ll repost them
Right clicking on an organelle would open a menu, which puts all the important features related to messing with organelles in one place. (but also means some features may require one more click than they would otherwise. imo that’s alright because organism editing isn’t intended to be super speedy, but rather deliberate)
I also made a sketch of the organelle customization menu, and I don’t particularly have much to add there, except why should we restrict organelles’ lengths (and other parameters) to the values we set as the minimums and maximums for the sliders?
In my concept I added a little plus and minus button to let the player change its size outside of those limits, potentially letting them make their pilus/flagella/whatever way more massive than is remotely reasonable. Then it’d be up to auto-evo to decide whether or not it’s viable, or if the costs of growing and maintaining it and maneuvering with it are too great, etc. And if auto-evo decides it’s viable then it’d be pretty cool to see giant cells with giant spikes swimming around
i had a dream once where I was playing thrive and I saw a pack of cells with glassy pili longer than their bodies all swimming in the same direction together, and I got the sense that the pili weren’t a preset part but rather something that was evolved emergently somehow and im not actually going anywhere with this i’m just rambling
