Currently, the order of the GridSplitter's unique Properties lack a certain level of flow between them.
For example, they currently are, in this order:

PreviewStyle
KeyboardIncrement
Resize Behavior
Resize Direction
Drag Increment
Shows Preview

In this setup, for example:

• The user chooses what Preview Style they want to use at the top of the list, but whether they even want to use the PreviewStyle, is at the very bottom of the list, separated by 4 unrelated Properties.

• The Keyboard Increment and the Drag Increment Properties are separated by Resize Behavior and Resize Direction. Keyboard and Drag Increment are very closely related, whilst the two options separating them are irrelevant to the Increment systems used.

• The Resize Behavior's behavior can be impacted by the Resize Direction (the Resize Direction can overwrite the Resize Behavior's 'BasedOnAlignment' option to automatically dictate which direction to resize in). However, the Resize Direction, which has some authority over the Resize Behavior, is placed after it, and not before it.

Therefore, I would suggest this re-ordering:

PreviewStyle
Shows Preview
Resize Direction
Resize Behavior
Drag Increment
Keyboard Increment

If you end up making these changes, please DM me (Dorian), as I'd really like to update the Documentation to reflect how the options appear in-app. ( https://www.noesisengine.com/docs/4.0/Gui.Studio.Documentation_Element_GridSplitter.html#overview )
