Great concept but slow and buggy

I am impressed by the concept of IE.
However, for a production system
it is too slow and there
are too many bugs still in 1.2.
Examples:

* Moving items in the piece window
crashes the program often

* Inserting Repeats crashes the program
always (infinite loop of error messages)

* MIDI real time input does not work
properly. (I guess the quantization
settings are simply ignored)

One thing I could not find is how I can
change the spacing
of staves/verses/dynamics in
*all systems* consistently.

Best regards, Joerg.
