Description Brian de Alwis

The New/Import/Export wizards can become a bit unwieldy once many plugins have been installed.  It can be useful to open one of these wizards showing only a subset of the available wizards, particularly from the Welcome page.

For example, the new EPP for JavaScript developers has 14 categories of wizard,  

The New wizard allows opening on a particular category (see org.eclipse.ui.internal.handlers.WizardHandler$New).  This category can only be configured programmatically.  The org.eclipse.ui.newWizard command does not provide a parameter to configure this value.

I propose adding a new command parameter to the New, Import, and Export wizards that supports a comma-separated list of category identifiers, and to add support for the wizards to use those identifiers.
