How we can customize a website through Content Manager

[Ajey]

Hi all, I have created one website and linked it to one of the Product Store. As you know that there may be changes occur for the contents of the website. I, therefore, wish to know whether there is any utility available in the Content Manager of OFBiz with the help of which we can customize my website from the admin panel like adding new FTLs, XMLs, Images, customization of Leftbar, Rightbar etc. Please suggest me the appropriate solution, if u have any. Thanx, Ajey.
