Splitscreen Tools arrangement

In the transcription interface, there is a drop down that is visually separate from the split screen tool and it would be better atop the split portion.

In the workspace, I would prefer a single button to open/close the screen and even then perhaps only if the number of tools available exceeds some number. Then the top of the split can offer the options.

If we are putting tools into a dropdown for the user, it makes more sense to have them all in the drop down with the resulting action related to the type of tool rather than forcing the user to know what might happen.

Additionally (maybe for a different issue?) the tools in the split all seem to be slightly oversized (perhaps just a box sizing issue) and leading to a double scroll bar.
