Lists for InVision's Craft Plugin for Sketch

This is a collection of lists that I have created for use in various UI design projects. They are intended to be added as custom types in text section of the Craft plugin from InVision. Although these were made as part of my Sketch design workflow, they are simple text lists, so I am sure they can be used for other purposes as well. Contributions welcome!

Sketch Image Compressor (Beta)

A Plugin for Sketch that compresses your bitmap assets, to keep filesize to a minimum.

Please note that the compression is lossless, so no pixels will be harmed by running this Plugin : )

Installation

Download Sketch Image Compressor & unzip it.
Double click Sketch Image Compressor.sketchplugin to install the Plugin.

This is what Craft does:

function loadFramework(pluginRoot) {
  if (NSClassFromString('PanelsManager') == null) {
    var mocha = [Mocha sharedRuntime];
    return [mocha loadFrameworkWithName:'Panels' inDirectory:pluginRoot];
  } else {
    return true;
 }

	tell application "Finder" to quit
	tell application "System Events" to do shell script "defaults write com.apple.finder AppleShowAllFiles -bool true"
	tell application "Finder" to launch

	-- copy file to clipboard
	tell app "Finder" to set the clipboard to (POSIX file "/Users/zhangyongkang/Desktop/Markdown.md")

	### Points and display type

	PPI is points per inch below, not pixels per inch. Not all models are listed, just the first model with a new display size. Diamond, RGB Stripe and Pentile RGB refer to the subpixel patterns.
