Image preview #458
Description
It's great that you implemented image support, however, the usefulness of the feature is limited since there is no way to know which image is which. Do you think you might implement image preview support? Since you already work with pixbuf to save the images, implementing it should not entail any substantial changes to the codebase.
Also, it seems #457 has implemented something of the sort, though arguably it doesn't look like they put much of effort into it. It looks like they did not even bother to write comments in English instead of their mother language. Still, the code seems to work, so maybe you could borrow some snippets from there.
