Hi, Perhaps you would consider including a new block meta for an atmospheric re-entry way of O2 auto-replenishment for planets with breathable atmosphere. By adding Atmospheric Intake blocks like an external ventilator. On that note also it would make logical sense for advanced suits to take in oxygen from breathable atmosphere as well. There will still be the original meta of needing to Maintain O2 stores for extensive travels, as well as manual use of O2 machines to replenish in space. This will just reduce the overhead in micromanaging, and would be an improvement in QoL in general while maintaining logical sense.
