Hello lianergoist and welcome to the forum.
Yeah, most of the features you listed are set to be introduced in future versions. In particular, the auto-selection of width x height could be immediately introduced in the May release. The real time video feedback, instead, is more difficult to implement and would also require an internal codec modification but, again, it is also set to be implemented.
About the automatically selected bitrate, this is a our choice since this is an average helpful value (consider HD videos on poor devices), but maybe we will deploy a better algorithm to fit all the devices.
Thanks for your ideas and your reporting.
