Some examples and screenshots:
The Aligned Local Vector in the Vector Orientation modifier:
If use the Local Vector, the result will be as follows:
Improved the Wind Animation modifier:
The Looping animation feature:
For example, the Period = 50, then you can compare the frames 0 and 50, the trunk and branches should be identical. You can also compare for example frames 10 and 60, they should also be the same.
Accordingly, for recording cache or proxy, you must use frames 0 ... 49, or 10...59, etc.
To change the Period value you can customize the following settings: Stiffness, Scale Frequency, or the Wind Speed in the fan settings. If you changed any value, to fully update the period value click the Update button to recalculate the model, or just move the time slider.
To create a looping animation of the tree, you must determine the total period of the loop. For example, it will be 200 frames. Then adjust the wind of the trunk so that its period is equal to 200. For other paths, adjust the period value is equal to a multiple of 200, for example 100, 50, 25, 10, 5, etc. Ie for the branches, Period = 100 or 50, etc. For the leaves, you can set the Period = 10 or 5.
Also, please don't use the animation of the wind speed, or other parameters, and don't use the Perturb options in the wind object settings.

The Eraser modifier:
The Invert lines button allows you to invert the list of erased lines. This can be useful if you want to erase all the branches except for a few.
