mixlNavigator is a sheet navigation and guide tool for large spreadsheets where the column headers extend beyond the width of the screen. The add-in assists in maintaining row position whilst enabling rapid navigation across your worksheet to the select column. There are two features that will also help you with rapid column selection, the first is the ability to sort the list of headers and the second is the ability to store lists of unique headers that can be saved within the add-in mixlNavigator. The add-in also features a line guide which has two modes, one is 'Dynamic' where the guide will move with cell selection and the second mode is 'Static' where the guide will remain stationary. In the Stationary mode the guide can be adjusted to highlight and focus more cells as you navigate across the sheet. The line-guide color and thickness can also be adjusted.
