There are some error messages, and perhaps other places (I can't recall) in Firefly where image displays are referred to as "plots". I think this is a potentially confusing usage. "Plot" in the context of an application like Firefly that mixes image and tabular data is much more likely to be understood by users to refer to visualizations of tabular data such as scatterplots and histograms.

It may be useful to attempt a global search for message texts using the word "plot" in Firefly and assess whether they are being used in this manner.
