Google Docs/Sheets-like collaboration

We're currently working on building out our Estimation system in Retool.

I'm quite excited, it's a beautiful piece of software.
Only issue- live commenting and collaboration which we've had in Google Docs and Sheets till now.

For example-

  • commenting on specific cells in a table to update values,
  • Comment on specific text to change things
  • Comment on specific components containing values.

For example- "@person please update the sales Tax to 8%"

I have a live editor working in one of my apps. Not quite what you are looking for on a per cell basis, but it might be a blunt tool to fill the need.
