[FEATURE] the ability to add placeholder steps that describe the functionality i want to add at a future date

**Describe the solution you'd like**
It would be super nice to have the ability to add placeholder steps that describe the functionality i want to add at a future date.

Sometimes I'm building out a workflow and I had an idea for how to update/improve it, but don't have the time to do it right at that moment. so it would be nice if we could just add a placeholder step to remind myself to do it in the future.

**Do you have a workaround?**
Are you able to tackle the problem with an existing workaround, or can you not move forward without this feature?

**Comparable features in other tools?**
Is this feature or one like it available in another platform? If so, we'd love to hear what you like about that implementation.
Not quite similar, but n8n has the ability to leave notes anywhere around the workflow canvas which allows me to keep track of future updates I want to make and put the note in a position related to where that future step will go.
