Is it possible to turn off the scenes button?

Yes, it’s possible. Any control can be hidden by css as an example

The link above requires a password to open it.

The proper way to do this is probably within the CSS code, and I can’t help with that.
A HACK is to just leave the Title empty in the scene. NOT the name of the scene, but when you are editing the scene. There is “enable” then “id” the “title. I played around and if that is blank it seems to work okay, but does not show up. I also tried putting in a “null” character, which works, but the box still shows up in some “Widgets”.
If it blows things up, I said it was a hack. (You can always change it back though.)

OH! I just tried something easier… in the same place all you have to do is click the checkmark for enable/disable title! No checkmark should give you what you are looking for.

I see the author replied while I was typing, so his advise is probably best!

thanks. I’ve added CSS:

.ipnrm-btn.ipnrm-thumbs {
display: none !important;
}

it works.

BUT – it doesn’t work in your plugin Custom CSS tab. I had to put the code in the wordpress template settings.

It should. Check the enable/disable button inside this section
