+
+This node accumulates feature values over time, creating a cumulative effect. It's useful for generating gradually increasing or decreasing effects based on feature intensity.
+
+The accumulation process works as follows:
+1. For each frame, if the feature value is above the threshold, it's added to the cumulative sum.
+2. If the value is below the threshold, the behavior depends on the `skip_thresholded` setting:
+   - If True, the original value is kept (useful for creating "gaps" in the effect).
+   - If False, the last accumulated value is maintained (for continuous effects).
+3. The accumulated values are then normalized to fit between the specified `start` and `end` values.
+
+Use cases include:
+1. Creating gradually intensifying effects based on audio features
+2. Generating cumulative motion effects in response to video analysis
+3. Producing threshold-based triggers that build up over time
+
+Outputs:
+- Processed FEATURE with accumulated values
+- Visualization of the accumulated feature (IMAGE type)

 ##### 🆕 Recent Updates:
+- 10/3/24 - **FeatureAccumulate**: Adds a new feature modifier that accumulates feature values over time, creating a cumulative effect.
 - 9/30/23 - **FlexVideoSeek Node**: Added a new video manipulation node that allows for dynamic frame seeking based on feature inputs. This node enables creation of time-warping effects, music-reactive video manipulations, and other temporal distortions.
 
 - 9/30/23 - **Audio Utility and Effect Nodes**: Added a comprehensive set of audio processing nodes:
