I have found a temporary solution for the Home Button missing.
Open the home button
Copy the page address
Go to the bookmarks bar and click add a site
The URL of the Home Button/Speed Dial page will be in the dialogue Box
Opera://startpageshared/
You now have a bookmark for the Speed Dial page that you can use like we used the little squares icon before.
Let me know if this doesn't work, I might have missed a step.
