Sure: It has some bugs and the interface is not yet final, but given that this is a very early beta, that is to be expected of course and is totally normal :-). Some have already been ironed out with the new version.
If you look beyond that: The tool is already useful for its intended purpose, as it allows exporting (which works fine) and the result can be tuned in other software as well.
I like it and looking forward to further development. :-)
