How to create a custom design of an existing view block? I have a block I created via views ui. It is in a table format. It has 3 columns with 3 fields. Every field shows in a separate column.

Now I want to change the design of this block in an easy way to my likings.

For example here is the screenshot of one of the blocks to explain what I mean. 


This shot is showing user-pic, username and follow-flag resp. As indicated in the snapshot, I want to show follow-flag below the username.

How to easily change the design of my view or block? The best would be a drag &amp; drop. I guess this is an easiest way.
By modifying the view templates the views can be altered.
You can add custom html design and styles to modify design.

From Page: Theming information select the template. For eg:  views-view--sample--page.tpl.php, template for the view named Sample.
