Formula Editor

[DannyGelf]

Is your feature request related to a problem? Please describe.
Since Better Formula was taken off, no formula editor does half what it used to do... The closest thing is ORGanizer formula editor but it's quite bad, just formats the spacing.

Describe the solution you'd like
I would love to see a VSCode-like interface on the formula editor, enabling:

1. Auto-complete fields
2. Auto formatting
3. Validate the formula on the spot (with some delay)
4. operators and functions selector and helper
5. Bonus - Diff mode to see the changes BEFORE starting (the existing one) and before saving
6. Bonus 2 - AI assistant with ChatGPT key (but only as optional, the one that was on better formula was quite annoying as 95% of times I don't need AI assistant)

Describe alternatives you've considered
ORGanizer, but it's no good.

Additional context
Better formula interface - also @SantiParris8 has the code of this extension in its minimized version

I would love to have a VSCode editor on the Data Export. Column name suggestions is going to be unreal.
