Suppress text column hints - If the width of a column is such that there is more text to display than can fit in this width, then GSAK will by default show a "tool tip" type of hint when you hover your mouse over that cell in the grid. If you find this distracting you can turn off this behavior by checking this box.
Elevation suffix - The grid display of the column elevation defaults to showing a suffix of M for Meters or F for feet. Here you can alter this suffix, or remove it completely.
Show partial rows - Controls the grid such that the very bottom row always shows in full or only partially. For more information about this feature see this link
Grid row height (pixels) - Enables you to change the default grid row height. For more information see this link
