PI - Absolutely. Being able to see in real time when my extractor cycles are going to finish would be huge, especially since i prefer short cycle times over several day long ones. And if i could tell the extractor to restart without being able to modify the settings that would be amazing too.
Fitting tool - would be super useful for theory-crafting outside of the game, like when i’m on break at work and want to see how a fit looks on paper. but might require a lot of memory space ( who knows )
Calendar - useful idea, i never personally use it but support 100%
