Improved clarity around the "Sheet Column" in the Column Mapping. It now shows "Select a Column" instead of "Select a Field" and "Add New Column" instead of "Add Custom Key."
Fixed an issue where reconnecting a feed to a spreadsheet would not save in some cases.
Fixed issue where rows could be inserted in incorrect columns.
Added new icon to open spreadsheets from the Feed List.
