Display Blog Categories horizontally not vertically

Hi

I have set my blog to display a list of Categories. By default this displays in a vertically ordered list (see attached Categories -current.jpg).

Q1) Is it possible to change the layout so they items display horizontally until they reach the width of container then wrap to a second row as per attached Categories - Desired.jpg?

Q2) Is it possible to have an "All" option which shows a total count of blogs and allows anybody who has applied Category filter to get back to default view again?

Thanks
Peter
