Thank you very much for making this plugin @a.peter. Just what I was after in order to sum up the amount I have spent on all my books. I can also work out Australian dollars and Japanese yen. Now I don't need to export the data and work it out, although after working out the amount I've spent on ebooks with your plugin ...maybe I don't need to know
I have spend over AU$5000 on ebooks/manga, although I'm sure others have spent a lot more.
Suggestion for additional feature:
- Being about the filter the count (costs in my case) using other columns like author, tags or source. You could currently do this individually if you filtered before you counted, but it would be great if your plugin could also do the filtering and display it filtered.
