Thanks for the feedback Kevin.  It's for sure something we'll need to look into. 
As for getting back the section in the 'Customer List' screen, you will need to copy/import those screens from another account since they are no longer exist in your account.  Here are the steps I would take:
 
- Create a new Method account.  Use the same information you were provided with in the initial setup email.  You will need to pick a different name for your Account Name.
 - Use this Method account to keep a backup of how the original screens look.  That way if you need to revert back to a screen or section, you can. 
 
Now to copy/import the screen into your account, follow the steps below.
- In your current Method account, click Customize > Screens.
 - At the bottom of the screen, click Copy/Import Screen.
 - Click Another Account.
 - Enter the Account Name, User Name and Password from the new account you just created.
 - Click Next.
 - Click the Screen Name dropdown list.
 - In the Save As box, type in the name for your screen.  
 - Click Next.
 - Ensure that the ‘Add a Tab Link’ option is selected and that ‘Home’ is selected for the Tab dropdown list.
 - Click Finish.
 
That’s it!  If you click on your ‘Home’ tab, you should now have your Customer List link back.
