iPad Home Button for Safari - how to add one

Well, the short answer is that you can't make a home button directly in the Safari toolbar, but you CAN add one to the bookmarks bar. Here is my iPad showing the home "button" just bellow the back button. Clicking on the Home link takes you back to the home page without opening a new window.

Here is how to add the home button:

Go into settings, then Safari and select to always show the bookmarks bar.
Navigate to the page you want to set as the home page.
Click on the add bookmark button.

Change the name of the page to "Home".

Click where it says "Bookmarks" and make sure this is selected as "Bookmarks Bar".

Then click "Save"

You should now have a Home button (link) on your bookmarks bar.
