Right now, it looks the Gantt view only supports Finish-to-Start
However, I'd like to be able to track Finish-to-Finish
The "workaround" to do this would be to further split by deliverable's final step that is actually dependent on the dependency. However, this generates a lot more data and linkage that makes the everything orders more difficult to both manage and digest
Start-to-Start is one I can find some use in, too, but Finish-to-Finish is very common
Smartsheets is capable of this and summarizes everything well here: https://help.smartsheet.com/articles/765727-enabling-dependencies-using-predecessors
