# NOW
## Chores
- Blending modes
- actually write the blending modes (everything is just alpha over right now)
- Node groups
## Compositor
- Playback...
- Manage Samplers -- (Resources in general)
- Blender previews (important)
- Blender previews (important !)
- Data model for comps
- Dump and read back state, (de)serialization!!!
- Non-negotiables:
- Text (idea: index-based evaluation in plugboard)
- Shapes (idea: embed glisp :mmtroll:, need to inquire -- still a lot of friction for simple shapes if we don't also get the glisp tools)
- External data driving (json or something else?)
- Pre-compose
- Shapes (idea: embed glisp :mmtroll:, need to inquire -- still a lot of friction for simple shapes if we don't also get the glisp gizmos)
- External data driving (csv, json or something else?) -- use a node to select source
- Pre-compose/Layer Groups (jokes -- can be completely UI side)
- Motion blur
- Layer Groups (jokes -- can be completely UI side)
## UI
- Viewport gizmos (Layer-specific & nodes -- can separate into different tools?)
- Viewport gizmos (Layer-specific & nodes -- can separate into different tools?) -- Not sure how to go about this
- Node loop detection (separate DFS (extra work) or be smart in recursion)
- detect time-sensitive nodes in tree and display on timeline
