It would be awesome if there came a possibility to build a song in a linear way, by placing patterns on the grid (just like the arranger in Deluge).
That would make it much more fun to build a song and also much quicker and you get a more visual overview of what plays when.
Also it opens up possibilities of selecting a section of the song and loop only that section, or jump to a different section while playing.
It would also allow for recording your performance (launching patterns) into a song.
