Squirrel Finder modifications

I have been modifying squirrel finder many times for my use, and it has never failed me.

But now, I want to know how I can create an array/table like thing. Currently, squirrel finder positions each new MC/XML data block vertically, but what if I wanted 2 columns, or 3. How can I do that?

As a side question, is it possible to create two buttons (arrows), that when clicked, will load the next or previous “x” amount of entries?

Thanks
