Thank you! Im not sure i understand the question fully.
Zooming out would be setting the zoom attribute less than 1. You can set that number to any number at any time. This way of zooming doesnt need to "prepare" zoom like the old extension
Im waiting for 4.0 build to update this and see what issues it still has.
Has anyone added anything or cleaned up the code at all? Or should i use my version still?
Upload here if anyone has worked on this.
