Give one loop the ability to be both horizontal & vertical for instances like a hall that would be T or L-Shaped, so in the image attached have the one part of the loop in the yellow box to be ran vertically while the horizontal part beneath the box stays horizontal

Underfloor heating - Would be great if we could draw which way the F&R transitions to the UFH zones go, just like when we select multi pipes for radiator panels we should be able to draw the start of the loops, currently H2x picks the transition zones and most of the time its wrong and uses far more pipe than necessary. Also being able to add zone points like wall points would be great and a UFH schedule showing details of each zone and the required flow rates.

Ability to click and drag and move a loop to better fill a room
