Hi,
First : Thanks for this innovative (and useful) plugin.
I've tried it. I've noticed some issues.
- If you pick a portrait orientation, the row and column kind of mixup.

I should have 8 line, but I don't. I should have 4 column, but I don't.

- The other issue is in the tab navigation in the param window

Would it be possible to add the menu in the layout menu ?
Would it be useful to add an option for the user to specify a ratio between row and column ? Just asking.
Thanks.
