Edit: Above link seems to refer to CS6, in the meantime some of the Scripted Pattern features have been moved to Filter > Render, but the principles should still apply. Maybe this can also help: https://forums.adobe.com/message/4570439#4570439
Oh awesome, I guess I totally missed the changes to shift F5 fill options. I've been just using the pattern layers from the layer panel for quicker update of patterns. Thank you for pointing me to this.
For my purposes though, it would streamline my workflow quite a bit if the scripted patterns could be integrated into the pattern layers and allow for inline editing of the pattern. Very much like illustrator isolated symbol editing.
