just added my first recipe and found myself scrolling up and down the grain list looking for the right one. I was thinking it would be nice if there was some type of search tool

Good idea! It could be like how it's done with hops.

But of course, then it would make more sense to start with the type of malt and move the country of origin to the end. Like "Pilsener - Germany" or so.

We are looking into build a ferementable selection screen that would address this.
