suggestion, if you find me annoying, then i should say - i’m registred user 
but i had to ask my english friend to buy renoise…
i just thought how about “gliding” parameter in sample’s properties (or might be in instrument’s). it could be quite useful for acid loops for example or some strings and lead types of sounds. of course it can be done with 05xx command, but i just thought that i can’t use that in live playing.
and another one: make play current note if effect is 09xx (offset) and when you’re trying to change parameter of the effect. i just think it’s quite useful when you’re searching for necessary offset.
