Feature request: index expression

[ltdptel]

It would be very useful to add an index expression variable that works similarly to AE.

How it works

• Each layer gets a unique index number (starting from 1)
• The expression index returns this number
• For example: 5 rectangle layers with index*15 in would return 15, 30, 45, etc.

Thank you!

Checking the usage example I could propose you to use "duplicate effect" but at the time of writing it only supports translation..

I proposed a PR here in case you want to check that adds rotation support:

I know your suggestion is different but you might cover some of your needs with this update.

Using an index in expressions can be extremely comfortable and powerful.

For example, you could create a sine wave from circles. It would seem to be done like this:

translation X: index*100
translation Y:Math.sin(time*Math.PI+index)*100

Example

"Duplicate effect" won't work for this, but it's useful anyway. Thank you!

(Well, it is possible to manually assign an index to each object through properties, but this is cumbersome, inconvenient, and slow)
