What native PinePhone application would you like to see in the near future?

[TRS-80]

I would like for at least one of the browsers to support DRM decoding for Netflix, Disney Plus, etc

IMO, Digital Restrictions Management is not a desirable "feature" and should not be "supported" in F/LOSS.  In fact, I would politely suggest to stop using "services" from any company who are so obnoxious as to think they deserve to run unknown, proprietary code on your device, just to protect their private, dinosaur business model.

The fact that so many people were/are willing to go along with these schemes was what ultimately led to Android and many other OS and devices becoming completely locked down, unusable trash.  Therefore I am not a fan of this sort of stuff creeping into GNU/Linux.

EDIT: 

Re: OP

I think that anything which is potentially available as a web interface should be lower priority.  Particularly if it's a well designed, responsive (i.e., mobile friendly) interface.  Not that I prefer web interfaces of course, but rather it's just a matter of prioritizing, at least at first, anyway.
