Spreadsheet. As in Character sheet, Handout and Spreadsheet.

Spreadsheet native to Roll20. As in Character sheet, Handout and Spreadsheet. Multi tabs, readable by the API, basic spreadsheet functions.

Embedded googledoc sheet would be more awesome.

I would prefer a built in spread sheet system. I don't to have to link accounts and such. It also would force the Devs to add Google's API to their system and make their own API interface with it (which might not be fun or easy).     I would like the ability to add a table do any document I have edit permission for. I could then add things like inventory spread sheets to each my players' characters.    If the scripting API is expanded like Stephen S. recommended then we could do make scripts for selling and buying items, auto distribution of money, and weight/encumberance calculations.
