 - Support a separate sound shader `.slang` file in shader packages. (https://www.shadertoy.com/view/XsBXWt)
 - Add WebView2
 - move to MSDF, typography rasterisation
-- better shader search UI
+- better shader search UI, pass 1
 - More comprehensive greenscreen shader
 - linear compositing?
 - compute shaders or a small 1x1 or nx1 RGBA16f render target for abritary data store
 - allow shaders to read other shaders data store based on name? or output over OSC
-- Mipmappong needed?
+- Mipmappong for shader declared textures
 - unwrap a fish eyelens and mirror it and map it to equirectangulr for environmnet map purposes
