### Problem to solve
Make sure all ToDos in code in the Web IDE are counted for an easy visual if any ToDos remain.
### Intended users
Developer
### Further details
See [Stackify ToDo Parser](https://stackify.com/top-visual-studio-code-extensions/)
### Proposal
Add a simple counter of the number of ToDos remaining. This could be on the bottom or right side of Wed IDE.
### Permissions and Security
Consistent with existing permission. Information only.
### Documentation
### Testing
Minimal risk since info only - no action is taken by the Web IDE.
### What does success look like, and how can we measure that?
Success is the number of ToDos in the file count matches the ToDo counter.
