Snap! Jr: Snap! For Youngsters! (Version 2.0.0) (Part 5)

Also,

%n is a number input.
%dir is a direction spinner input.
%dst I can't remember.
%cst is a costume input.
%s is a string
Put %mult before any input to make it a multiple input list.
%snd is a sound input.
%note shows the note picker when the input is clicked
%clr is a color input.

There is more, but I don't want to explain all of them.
Also, you can do the variables category.

        // Variables
        doSetVar: {
            type: 'command',
            category: 'variables',
            spec: 'set %var to %s',
            defaults: [null, 0]
        },
        doChangeVar: {
            type: 'command',
            category: 'variables',
            spec: 'change %var by %n',
            defaults: [null, 1]
        },
        doShowVar: {
            type: 'command',
            category: 'variables',
            spec: 'show variable %var'
        },
        doHideVar: {
            type: 'command',
            category: 'variables',
            spec: 'hide variable %var'
        },
        doDeclareVariables: {
            type: 'command',
            category: 'other',
            spec: 'script variables %scriptVars'
        },
