This would be great. It is kind of what I had in mind when I suggested this: http://kendo.uservoice.com/forums/127393-kendo-ui-feedback/suggestions/2662536-add-grid-column-filters. I currently use this type of filter where the filter is just a free text field and upon blur or enter, it runs the filter. having control over the type of filter syntax used would be great ... so that it is Linq, List, Oql, or custom string compatible. This is a common feature in the Telerik Grid when used in client mode...
