HI @drchrisbridges – the best place to submit a feature request is at the Gitlab repository for satnogs-network. That’s also where code is hosted; you can find more details on how to contribute to software on the wiki.
Off the top of my head: #2 might be difficult at the moment due to the way that TLE updates are handled; see the earlier discussion for details. #4 I think is handled by the website – that is, if the data format for a particular satellite has a decoder in the project already, and if the recorded data is good enough, it happens automatically.
HTH!
