is it possible to remove the + button on the left?? i could be wrong but i think that there was one version of Oper that didn't have that button and we could add bookmarks using the heart.
You can still click on the heart. When you do a drop down menu open. By entering there you will find a second arrow within your unsorted bookmarks and at the bottom of the list is "Bookmarks Bar". Clicking on this will add the item to your bookmark bar bypassing the + at the left of the bar. However... I'm not certain you can remove that + button.
