The current 3D View Toolbar is very messy, in both Object Mode and Edit Mode. It's also become overly long, tool selection is spotty - some tools are there that probably shouldn't, and others that are there probably should not be - and it's inefficient to use.
The 3D View Toolbar can be greatly improved by simply reorganizing it and reviewing all items that are in it, adding and removing items as needed. This organization should be based on the new vertical toolbar tabs.
