Search function in Workflow Designer

Here's another idea: Add a search function in the workflow designer, so I can search for a variable name, or other text that I use in my code and jump to the activity where this text occurs.

Sometimes a workflow has many levels, which makes it hard to navigate. As a workaround, I now use notepad++ to search for text, and it gives me some idea as to where in the workflow I need to be, but that's not ideal.

Even better would be to be able to also replace text.
