Is a new version of renoise to be expected soon which fixes that stupid “first line not played and rendered” bug ? I (and I guess others) really need this.
Also, some more ideas for improvements :
the old things first :
clear the wavebuffer before rendering, because at this point you have delays and stuff which is still played in your rendered file when you press render,
disable midi-in when rendering.
also, some other things highly appreciated would be :
render per instrument, not track
render a selected range (also with some pre-run, means I want patterns 10-13 to be rendered, but there is a long sample which is started at the end of pattern 0f, so I would like to have an box like
play from position : 0f
render from postion 10
render to position : 13
maybe a box to disable/enable tracks in rendering
also, would be nice if the render window would auto-close after the rendering is finished.
at this point the rendering is far from being really useful, I am afraid. 
today I had to export some drums I made, splitted into patterns and also dividing the basedrum and the other drums, and it was a real pain to do that.
