Hi! I completely understand what you mean. Right now, Opera doesn’t have a built-in option to remove or fade the Speed Dial icons completely, so the theme isn’t fully visible.
A few tips you could try:
Use folders for your shortcuts to reduce clutter on the Speed Dial.
Send feedback to Opera directly, they often consider user suggestions for future updates.
This way, you can enjoy the theme more while keeping your frequently used shortcuts accessible. Hope this helps you bro.
Good luck brother.
