I'm getting closer (or so it seems) to the next Sheetsee update. I'm excited about it! It will change a lot and take care of a lot of stuff I've been wanting to do for a while.
It will: allow you to paginate your tables, use polygons, lines and multipolygons in your maps (and color them!), be modularlized so, if and only if you want, you can just build the parts of Sheetsee that you want to (ie: a version with just tables and maps).
I've got the modules in their own cozy repositories on GitHub and am working on the modules
branch of jlord/sheetsee.js, which will remain the main repository with all documentation and the full version of sheetsee for users who don't wish to build a custom one.
Here is my to-do list, mostly for me because I wrote it on paper and then lost it, but also for you, if you're interested:
