We are back after a long time. We have a few enhancements and things to fix in our road map (https://github.com/numeroteca/pageonex/projects/1). They are basic features to extend the use for an easier and deeper
analysis (drawn areas would be able to store more data, not only the
topic). Juanjo Bazán will be developing in RoR.
Check the post with all the extended features we had planned that we presented for a grant last January (that we didn't get):
We didn’t get the grant to develop new features but… look how cool they are!
