Offer columns in checkbox layout

Thanks jcisio, Katou & codexmas; great module.
I use some custom css for the display of the terms on one my sites and wondered if you might consider a way to integrate it into your module.
I worked out a way to display the taxonomy checkboxes in columns on node edit pages and I thought there may be a way to build an admin interface for it. The key elements would be the taxonomy id and how may columns or column width the user wanted (cols: width || 1: 100%, 2: 42%, 3: 26%, 4: 18%).

For example for vocab ID 6 I use this to create 2 columns:

.taxonomy-super-select-checkboxes div[id^=edit-taxonomy-6].form-item label.option {width:42%; margin-left:3.5%; text-indent:-24px}
div[id^=edit-taxonomy-6].form-item:nth-of-type(2n+2) label.option {clear:left;}

The first declaration sets a width and formatting that creates two columns.
The second, clears the float after every 2nd checkbox label.
I don't need both statements, either one will work but both cover all the bases.

3 columns would be:

.taxonomy-super-select-checkboxes div[id^=edit-taxonomy-6].form-item label.option {width:26%; margin-left:3.5%; text-indent:-24px}
div[id^=edit-taxonomy-6].form-item:nth-of-type(3n+2) label.option {clear:left;}

Here's all the css together with the 3 col option commented out and a 1 col option (vocab ID 11) that displays on the same page:

/* taxonomy-super-select taxonomy terms
---------------------------------------------------- */
.taxonomy-super-select-checkboxes .description {clear:left;}

/*put check boxes in 3 columns
.taxonomy-super-select-checkboxes div[id^=edit-taxonomy-6].form-item label.option {width:26%; margin-left:3.5%; text-indent:-24px}
div[id^=edit-taxonomy-6].form-item:nth-of-type(3n+2) label.option {clear:left;}
*/
/*or 2 columns*/
.taxonomy-super-select-checkboxes div[id^=edit-taxonomy-6].form-item label.option {width:42%; margin-left:3.5%; text-indent:-24px}
div[id^=edit-taxonomy-6].form-item:nth-of-type(3n+2) label.option {clear:none;}

/*set check boxes one per row*/
.taxonomy-super-select-checkboxes div[id^=edit-taxonomy-11].form-item label.option {clear:left;}

The theme I used is a customized Newsflash theme but I've tested it in Garland too.
