59:T451,

This lightweight addon improves the transmogrification UI to work better with partially collected sets and much more!

Features

Many of these features can be configured via the "Filter" button on the "Sets" tab.

Sets tab changes

incomplete sets are no longer faded out and reflect missing slots
when applying a set, the other (or missing) slots are hidden
set tooltips show how many pieces you have collected and which you're missing

Extra sets & filtering

see extra sets (e.g. lookalike sets from other classes that you can use)
filter by the amount of missing pieces
ignored slots (ignore slots you don't care about - they won't count as missing)
skipped slots (those are never applied, e.g. if you like to mix and match items)
hidden slots (those are always hidden - maybe you don't like helmets)
showing only favorite sets (and their variants)

(You can save the ignored, skipped and hidden slots per-character by enabling "Use character profile".)
