It would be helpful if some of your tools had an optional input. For example, the directory tool is of course very helpful at the beginning of a workflow, however I have several workflows that create or pull in files, rename them, edit them, etc. I then need the directory tool to check that folder for the newly created files and then to feed that downstream. The problem is that when I have the directory tool feeding into the workflow, it fires immediately noting that no files are in the folder. I would love if the tool had an optional input so you could choose to put it in the middle of a workflow in an attempt to force it to hold off on firing until its turn.
Even better would be if the dynamic directory tool would allow for dynamic folders to be fed in rather than pinpointing a specific file....since it has an input, that would suffice and the user could either pick the regular directory or the dynamic directory if they wanted it to fire off in the middle of a workflow.
