It could be useful to add a setting in the current Excel filter, allowing to specify a column whose cells would be imported as CafeTran Notes (not following the segmentation rules). I don’t think those would need an export, as they are just for reference. This could be useful for easy access to context notes, references, and other useful information provided in a separate Comments column.
One current solution is to open an HTML version of the file for source preview. Although the columns display is not perfect, it still gets quite usable by tweaking page Zoom.
What do you think?
