No, currently there is no way to turn the feature on and off. To work around this, you can do your on-device testing using an Android device (which doesn’t have the preview menu at all), or run an iOS release build (but then you don’t get live reload).
Thank you for your quick reply, Uldis.
I understood that. I’m gonna test the page on an android device for now.
But, honestly, facing the endless-preview-menu is the most disgusting moment when I develop with Fuse.
All other experiences with it are totally great, and I like it.
So, I will leave some feature suggestion in the forum.
