A few issues when shooting tethered

Hi All,

I have tried tethered shooting with a Canon 5D Mark IV and have issues and wishes for upgrade.

These issues are when in Live View using Pocket Wizard Mini.

1- Zooming doesn't always give me an in focus view. (not fault of focus setting on camera)
2- Zomming to 100% or larger makes preview thumb nail size
3 - Hitting shutter button doesn't fire strobes until second touch. So I have one blank image.
4- Color temp during live view is terrible. ( and kelvin in live view not supported for my Canon 5D MK IV)

Wishes for upgrades:

1- Make Canon focus points visible, selectable, and configurable like in Canons DPP.
2 - Speed up RAW capture view. Currently taking about 7 seconds. LR and DPP are faster.
3- Live View full screen no matter what zoom level
