Without wanting to unduly influence anything (I’m not an R&D engineer) - please feel free to make suggestions without worrying about whether they’re technically feasible or not.
More or less all the time, even our most expert users aren’t aware of how systems are built under the surface - so make suggestions that you feel will be helpful without worrying about whether they’re possible or not. We’ll work that out, and we always try to let you all know if things are definitely not possible.
I would also - (in my opinion!) - say that I think this is a good idea. Having the file continually save with headers intact would improve reliability and robustness. It’s not babysitting to have something easier to use and less likely to fail, after all.
Obviously even with this idea, it would be best practice to stop recordings manually - but it would provide a layer of redundancy if there was a power outage.
