=== Issues ===
 * Port list is filtered after deleting all the filter predicates.

=== TODO ===

 * Validate the MacPorts installation path
 * Progress indicator
 * Detailed progress log
 * Variants selection when installing

=== Nice to have features ===

 * macports.conf  and variants.conf preferences
 * Source list filtering (categories, state, …)
 * Support for obsolete ports
