• "Undeletable" point fix
  If, somehow, there are two points with the exact same coordinate, they will appear on top of each other, along with a midpoint (which of course is the exact same point as well). Previously, the midpoint was on top of the markers, making them impossible to delete (you'd just keep adding midpoints). Now, those markers are on top of the midpoint, making them easy to delete.

• Easier-to-use wiring zones
  Wiring zones are now easier to create than ever before. Rather than running out of subarrays because one loss value, or the original inverter, was different, all module, inverter, and loss settings are defined on the primary field, meaning you only use subarrays if you have a different layout setting for one of the fields in your wiring zone. Additionally, this enforces that all fields in a wiring zone use the same module for their layout.

With the "Simulate" button in the upper-right, you can run production simulations for all fields and view a design summary with the click of a button.

• Layer moving (works for both fields & obstructions): shift + drag.
• Albedo presets: used in engineering templates for bifacial modeling.
• OND imports: the long-awaited complement to PAN imports.
