Chocolate Factory for Chrome
More About Chocolate Factory
There's no way to select multiple packages on chocolatey.org.
Chocolate Factory adds checkboxes beside each command. Just check the packages you want to install and then click the Copy button at the bottom of the page. A single command for installing the selected packages will be copied to the clipboard.
Two more features of Chocolate Factory:
1) You can now click on the install command for any package and it will be copied to the clipboard.
2) Chocolate Factory also supports importing a list of packages. It accepts the output of the 'choco list -lo' command for importing your previously installed packages.
