 	WebGPU formulate is expensive
-  Mirror pass clicks bug
+	Mirror pass clicks bug
 
-  Minify bundles
-  Naming "matrix" for the github repo, "digital-rain" and "DigitalRain" for everything else
-  Minimum react requirement?
-  Retire fetchLibraries?
-  Move off of regl
-    Unify implementations?
-  Responsive changes
-    Move start time to rain object
-      Matrix component should record, then overwrite it
-    Reshape all passes to react to config changes, ie. "configure"
-      main.js "formulate" --> "configure"
-      simple deltas only require updating the uniforms
-      return boolean of whether all deltas are simple
-        Resource changes are simple if they're cached and loaded, false otherwise
-      remake the pipeline if anything returns false
-  Core vs full
-    core
-      One embedded MSDF, combined from the two main glyph sets and their configs
-    full
-      Other MSDFs and configs
-    and then one with built-in MSDF generation
-      (TTF + glyphString) --> MSDF
-        Is MSDF strictly necessary?
-  Expanded configurability
-    Modify regl pass
-      async build(config, inputs)
-        loads all required stuff
-      async resize - adjusts the sizes
-      run — performs the GPU operation
-    Rewrite main code to accept changes to config

 Build a Tweakpane for config

-    Hide after three seconds
-    If tapped, show the tweakpane

 Support Resurrections SDF bevel and "lights"
-  https://shaderfun.com/2018/07/23/signed-distance-fields-part-8-gradients-bevels-and-noise/
-  Get the "normals" and color right
-    Note: even completely dark glyphs can have glint on their edges
-    "Golden hour"
-  Stuff MSDF-derived normal vectors from rain pass frag into two of its output channels
-  Anomaly mode toggles between this and anomaly streaks

 WebGPU
-  Try https://github.com/brendan-duncan/wgsl_reflect
-  Get rid of end pass once it's possible to copy a bgra8unorm to a canvas texture
-  Switch to rgba32float somehow?
-    Why isn't this straightforward?
-  Try shorthand
-  Share a bind group and layout just for time?
-  Try using a buffer for the stripe pass 1D texture

 Improve loop support
 
 Idea: Build a UI
-  Replace versions with presets
-  Simple changes update the values
-  Complex changes replace the pipeline
-  Make it a form, so it's accessible
-  Then, make it look cool like the UI from the old site
