Is your feature request related to a problem? Please describe.
Results in the new search format for geography, locality and events are displayed across an extremely long table that cannot be read without scrolling back and forth. This image has been shrunk significantly show the empty columns.

This is what we see on a standard screen with typical magnification.

Describe what you're trying to accomplish
Make the UI easier to navigate for data entry volunteers

Describe the solution you'd like

1. It would be helpful for all searches but most importantly for Locality and Events search add two buttons like those on the bulkloader display: "Hide Empty Columns" and "Show all Columns."

2. Put data that tends to be less variable at the far right of the screen: e.g., Geography Authority, Geo WKT, Locality Footprint, Datum, Georef Source, Georef Protocol. This would put some of the variable data we're searching for (Depth, Lat/Long, Verbatim Locality, Verbatim Date, Began and Ended Date) closer to the Control column.

Describe alternatives you've considered
Put up with it as is.

Priority
Normal priority but very helpful for daily work.
