In the same way that Dynamic views and WorkApp resources listed on the left can be collapsed or expanded, I would like to see a searchable, sortable, vertical column with scrollbar that lists the headers of all columns in the sheet. Each column header name would hyperlink directly to the column I want.
I have 80 columns in my sheet and I don't always remember the column name exactly and I scrolling across 80 columns while trying to eye that one header is a pain. Sometimes I miss it over and over, or maybe I've hidden it and don't want to unhide every header to find the one I want.
