Well, for 10 minutes work, I would say the "Current Layout" works like a charm but I have a suggestion. It would be nice if there is an icons panel which replace the six selectMenu options. I can guarantee that people will get used to the icons.
I imagine these icons doing the following:
- select the given layout
- run the script
Thus, it would be even faster to switch between layouts and compare how your presentation varies.
Btw, it can be also regular buttons: 7P(Portrait), 7L(Landscape), etc...
My two cents.
