Make Filter Fields accept text with auto-suggest for Column selections

[RandomFractals]

similar to how aggregate and filter operands function now.

Description of Problem:

I would like to type a column name to filter on or group by without dragging it from the Columns left side panel for quickly setting up viewer data filtering, sorting & grouping config/settings.

This would be a real big improvement!

Definitely was thinking it would be nice if it was more intuitive. You have to thoroughly read that doc page at least twice which describes the column expressions
