     * To do: kill running scripts, e.g. when changing effects
 * To do: use Nodes arguments as arguments to scripts or hardcoded effects

+* Multiple Nodes can be defined (1)
+    * Each node can have properties (compare controls in WLED / StarLight)
+    * Each node can run precompile code or Live scripts (with or without loop)
+    * Each node has a type
+        * Fixture definition: tell where each pixture is in a 1D/2D/3D physical coordinate space (based on StarLight)
+        * Fixture mapping: change the fixture to a 1D/2D/3D virtual coordinate space
+        * Effect: run an effect in (part of) the virtual coordinate space
+        * Modifier: Mirror, rotate, etc, multiple projections allowed (projection in StarLight)
+        * Driver show: show the result on Leds (using FastLED, hpwit drivers), ArtNet, DDP, ...
+* Future situation: Nodes and noodles (2)
+    * Replace the nodes table (1) by a graphical view (2)
+* Mapping model (3)
+    * Take the StarLight PhysMap as a start
+        * 2-bytes to 3-bytes to allow for > 16384 leds
+        * Mapping table is logical pixels
+        * ledsP is physical pixels (as in FASTLED)
+        * 1:0, 1:1, 1:many : each logical pixel can be mapped to no, 1 or many physical pixels)
+    * Nodes manipulate the mapping model and/or interfere in the effects loop
+* Presets/playlist: change (part of) the nodes model
