I just pasted a YouTube video into my board, and instead of it showing in a normal ‘link box’ (with the title and thumbnail). Now it has a button to go to focus mode, I think this is called an IFrame??
But what I hate about this, when I zoom out it shows a large YouTube button that keeps getting bigger. I don’t care about that YouTube video right now, why is it trying it’s best to get my attention?! I could see this getting extremely frustrating when I have 50+ YouTube videos and other things linked in my board, and they all take up space when zooming out, I can’t even get an overview of my board anymore. The timeline does the same thing, I know where my timeline is, I don't need a giant Icon and label telling me it’s still there. There should be an option to set the default paste back to the normal style, and also just to turn these buttons off when not necessary.
Image example, I have a lot of YouTube videos on my board, and I’m glad they currently don’t all have a logo, but I don’t want this problem to get any bigger than it currently is:
