performance in 1.2

Hi. I already described this in detail in another post:
With many edits and audiotracks, the interfaces and the scrolling gets VERY laggy, at times almost unusable.
Will this be adressed in a future update?

Yes, this is a showstopper. The lag in the gui is really bad. Feels snappy at first but when a project grows so does the lag until it is so bad that one just gives up. This needs to be be fixed. I’m using an iPad 3 by the way.
