I must agree, a feedback parameter is a must and also more than 4 sec.

Additional to that 2 wishes a tempo syncable LFO to modulate the delay time would also be a thing on my wishlist, so we could make a modulated delay effect.

B.t.w. i already bought it 🙂

This plugin could have killed a bunch of others out on the market but with the missing parameter controls it just misses the mark. Seems like Eventide doesn’t want to stray beyond what’s in the original algorithm even though they could. Oh well. Funds going elsewheres.
