People could use them for what ever they wanted. I'm sure others would have a few ideas for symbols. It is something very visual for people like me.
I have an idea that might work out here. It would also satisfy some long-running enhancement requests.
I think I can make calibre use a custom icon image for specific values in the column, probably by using the column's coloring specification. If the color is "something.png" (but without the quotes) instead of a color name, then when calibre sees the corresponding value it would use the image instead of the value.
You would put the file "something.png" into yourCalibreConfigFolder/resources/images, the same place that custom toolbar icons go. If calibre cannot find the image then it would display the text.
These custom icons would be displayed only on calibre's spreadsheet. They would not be displayed in the content server, book details, or other places that display values.
Is this a change that would interest people?
