It would be nice to have the option for a single filter input that searches all columns on the Grid. I was able to implement my own custom solution but having to apply that to every grid in my app is cumbersome. I understand the importance for the flexibility side of having each column with its own filter box, but for simpler apps this is overkill and a single filter box is enough. The column component already has the [filterable] flag so this can possibly be used to exclude any columns if necessary. I was thinking of something similar to what is an out of the box feature for the Datatables JS plugin https://datatables.net/ Default search box that searches everything. Very simple to use and understand for basic users or when your application only calls for something that simplistic.
