This change moves toward consistency with other properties windows allowing you to move the properties window of a fill layer. This is the first step in trying to make fill layers more interactive. I will continue to work on this so that you can see the color or pattern of the fill layer change as you change its properties, for example.
The new window can be called either as modal or non modal depending on whether or not it has existing layer data passed into it. This means that creating a new fill layer uses a modal window while editing allows you to move the window to the side to compare and contrast values.
Realtime updates to the fill layer would be nice and I will work on that next. I would also like to make this change to filter layers and others to try to make the properties windows feel more interactive.
Also, I'm curious to know how people feel about moving the properties dialogs so that they spawn closer to wherever your layer manager dock is (when it is available)? I'd like to streamline some of the properties panels to make them work more fluently with a stylus.
