The idea is to setup a layout like this:

[ total number of items]

||

[] Percent of leveraging of items n%

||

[ new item count  ]

[ used item count ]

and as the percentage is changed the new item and used item will be adjusted accordingly.

My question first question... how do I adjust the length of the vertical slider? I have found on how to do this for a horizontal slider, but not for vertical, and when attempting to apply something similar (height or width) I can't seem to get it to change. The default length is simply too long.

Any hints on this?
