Many settings in the GUI consist of a value that represents a tradeoff between two qualities. (Accuracy vs Efficiency, etc...) For these options, we should represent the selection with a slide bar.

For example, the 'k' value setting in the Classification options is really opaque. In order to make an intelligent decision about that option, you have to know what k-nn is, and how it works, and how big your data set is, and know how well different sizes perform, etc...

A much easier way to handle this is a slide bar. Based on the data size, we can make a good guess as to what we think 'k' should be. Then let the user slide the thing around lesser and greater. The bounds of the slide bar are what we judge would be max and min usable values. For 'k' that probably means 1 through sqrt(n) or something like that.
