Custom List of all items in Webform
Yeah, it sounds like you need to create a view to output submissions.

Webform helps you here by integrating fully with views so you can pull out whatever data you need. You can also create a view per webform which will enable you to have a separate page for each.

Failing that, if you go to Content Management > Webforms it gives you a summary of all webforms on the site with links to view submissions, export them, etc.

Hope this helps.
