Would it be possible to add support for Excel R1C1-style references to your Formulas plugin - particularly in relative form (e.g.
RC[-1] to reference the cell in the same row and the previous column), or is there already a way to do this? R1C1-style references would arguably make more sense than A1-style references in scenarios where rows and columns are not labelled with 1, 2, 3, ... and A, B, C, ...
On a related subject, can you give any indication when Formula support is likely to move from its current "not stable ALPHA version" (as described at https://docs.handsontable.com/pro/1.16.0/demo-formula-support.html) to a production-ready state?
(After writing this question, I did find https://trello.com/c/6HMfUvR4/62-improvement-formula-engine - which mentions R1C1 style and many other planned features. However, any other information you can share would be helpful.)
