UX - better field searching

Just some feedback - selecting fields to include in the Kibana Graph viz is pretty painful.

Would be great if it could take from Kibana's Discover field list, with popular fields and searchable function. Or at the very least, make the vertical height variable (when the Fields button is clicked could take over a lot more of the screen)

I feel your pain too :slight_smile:
Longer term we hope to align datasource selection with the "index patterns" already defined elsewhere in Kibana.
In the short term there are some styling tweaks coming that address some of the frustrations with the current approach.
