I customized my toolbar, digging through various menus to add the buttons I use frequently. Today Acrobat DC installed an update, and now my customized toolbar is back to the default. It's taking me forever to find the features I use and re-add them to my toolbar. I have deadlines! I have time pressures! I don't need this ****! I customized my toolbar for good reasons! Why can't my toolbar buttons stay where I put them???
