If I understand you correctly I believe you are looking for the indent buttons which you cannot seem to find in the new email designer.
This is because they are currently removed and I cannot say for sure whether or not our developers will add them back or not as they took out some of the editor tools that didn't get used as much to clean it up a bit in the new design. Some of which might be readded in future updates though I cannot say if or when.
However, you can still manually add spacing or modify it more accurately in the emails source code.
