Yep... I see what you mean. I do use my phone to view my alarm system at home, and both my stores... about 40 cameras. However, during the day I have a dedicated 27" display that keeps about 24 cameras viewable all day, and I can access the cameras on any of my computer, which makes them easier to see.
As for IP control... the only thing there is Roon and then the settings on my HTP-1, but have my small laptop for all that... remote would be too small. I mainly use my remote to power stuff up, change inputs and then skip ahead or back, FF/REW, volume, etc... when I'm watching Dish, Roku or movie media on the Panny.
Whole house automation is another level or remote control for sure.
