Maybe some day, but other than #6, these are all settings that are not memory-channel-specific. CHIRP's major focus is being able to move memory channels between dissimilar radios. If I were to support every feature of every radio, I'd only support three models and I'd be sick of it by now. If you want to be able to program every single bit in the image file, you should use the software that came with your radio. If you want to keep your memories in sync between your UV3-R and some other radio, you should use CHIRP.
Don't get me wrong, if you want to write the code to make CHIRP support the above features (or pay someone to do it for you) I'm all for it. I hope you understand that it's not something I can do for every radio in my spare time for free and still, you know, sleep :)
Thanks!
