Edit and Delete Customers

We need to be able to edit or delete customers from the database without having to upload a csv file. Below are a couple examples for when this would be helpful. I'm sure others here will agree that some simple database management would be greatly appreciated. I recently had to correct a type-o in a customer record and the process is just unreasonable. Download an example .csv file, add ALL the customer information (not just what needs changing) upload the file, and finally make sure that the original profile was correctly overwritten. It should be as simple as hitting an edit button, changing what needs changed, and hitting save. I have two customers with the same name. Lets call them John Smith and Smith Electrical Corporation. I send a package to Smith Electrical about once a month. John Smith ordered once from our website over two years ago. Whenever I type "Smith" when making a new order, guess who comes up as the first result! There's no need for John to still be in the system, why can't I easily delete his record?
