Frame Node Upgrade Summary:
- Custom Colors for nodes
- Presets allow common colors for nodes. A copy operator applies them to all selected nodes. See track colors in the clip editor for comparison.
- New theme colors for active/selected nodes (instead of using the single "Text Highlight" color)
- Bounding box behavior for the Frame node. Frames will make adapt their size to make sure all attached nodes fit in. An additional shrink setting defines if the bounding box is minimal or can be enlarged manually.
- Overhaul of the resize manipulators.
- The tiny lower right corner widget is replaced by reśize handle areas on the left and right border of nodes, so nodes can now be resized on the left side as well. (Note: regular nodes only resize in width anyway, any change of height happens automatically).
- Mouse cursor changes when moving over a resize area, as a convenient indicator.
- Frame nodes can be resized in all 4 directions (when shrink option is disabled).
- New operators for attaching/releasing nodes from frames (WIP).
