 iteration-composition.xml	Iteration, composition	Traditional loop constructs (while, until, etc.) plus the Lisp "named let" (a generalization of FOR) plus functional iteration (repeated invocation of a function) and function composition.
 list-utilities.xml	List utilities	Some standard functions on lists (reverse, sort, etc.)
 colors.xml	Colors and Crayons	Incorporates the former crayon and set RGB libraries.  Implements fair hues (more orange, less green, adds brown) and a linear color scale including grayscale and fair-hue-based shades.
+crayons.xml	Crayons	Just the crayons, without the rest of the colors library.  Fast and simple.
 bignumbers.xml	Bignums, rationals, complex #s	The full Scheme numeric tower.  "USE BIGNUMS <True>" to enable.
 cases.xml	Multi-branched conditional	Like "switch" in C-like languages or "cond" in Lisp.  Thanks to Nathan Dinsmore for inventing the idea of a separate block for each branch!
 try-catch.xml	Catch errors	Run a script; if an error happens, instead of stopping the script with a red halo, run another script to handle the error. Also includes a block to cause an error with a message given as input. Also includes a block to create a script variable and give it a value.

 word-sentence.xml	Words, sentences	One of the big ideas in Logo that they left out of Scratch is thinking of text as structured into words and sentences, rather than just a string of characters.  This library brings back that idea.
 strings.xml	Strings, Multi-line input	Extract substrings of a string in various ways. In general, text inputs allow only a single line.  The MULTILINE block accepts multi-line text input and can be used in text input slots of other blocks.

 signada.xml	Signada (Network remote control)	Interact with MicroBlocks devices via WiFi. Requires the device to have a TFT display, two buttons and WiFi capability, as well as the Signada MicroBlocks project loaded. The Citilab ED1 and a bunch of the M5Stack boards are some of the devices that work with Signada.
