I used chrome before, but after some update it started lagging like a crippled donkey. Maybe the newest current version runs smoother, but I think I`ll give Puffin a go to see how it performs.

As for the changes - Since some of us are playing on DMM as well, if there some new mechanics unclear feel free to ask either of us.

The auto-lock mechanic is super nice, since it makes sure you don't accidentaly sell off your newly gained 5*
It works ONLY for NEW 5* The system accounts for the fact you might wanna use the dupe for upgrading or selling off in the case of dupe event girls, so it does not lock those. A someone who was "this close" to sell of a new 5* once I appreciate this feature a lot.

Helenium - there are two versions of her. Normal and Easter. Both 6*. Normal has her Harp, and in the Boom artwork has a giant fuck off harp (don't really like that one, since it takes the focus off the girl onto the instrument itself). Easter has cute bunny ears bandana.
