It would be really nice if you could deselect a piece that you have just selected in the holdings.
OK, I now implemented this both in betza.js and betzaNew.js. (Every click in the holdings was treated as a first click, to prevent you could move pieces into the holdings, or between holdings squares. But a click on the already selected piece there indeed deserves to be an exception.)
@Fergus: I can no longer upload these .js scripts through the File Manager page of the Interactive Diagrams article. I get this error message:
Upload of /home/chessvariants/public_html/membergraphics/MSinteractive-diagrams/betza.js was allowed but failed! The cause of failure is unknown.
