Customer Account Update Formatting Problems

-- HikaShop version -- : 2.6.1

-- Error-message(debug-mod must be tuned on) -- : None

Please take a look at the "My Account" in the Nav tab on this site. On the first page with the icons, is it possible to format the number of columns so the 4 options are not so spread apart. I like the way your demo page looks. I can see that your account section is narrower because of the contents in the first column. But, I am just trying to get it to look better on our website.

Second, when I click the "Edit your account information" and go to the "Your Profile" page:

1. I see that you eliminated the "Personal Details" section. How? I would like to do the same thing.
2. I see the "Submit" and "Cancel" buttons on your page. But, they are not on mine. Where are these buttons controlled?
3. You appear to have rearranged the fields so that the User Name is below the Name field. How did you do that?
4. You also changed the titles for some of the fields and added the word "(optional)" in parenthesis. How did you do that?

Thanks for your help.
