I experience #4 very often running Redux on linux and #5 I have also wished for, well more a case of the phrases being exposed to the host so that they can be automated to change, I’m guessing as there will always be a different amount of phrases present so maybe the control would work in a range of 0.00 - 100.00% or similar?
Can be done via MIDI program changes or by using the keymap mode: seehttps://forum.renoise.com/t/trigger-phrases-in-redux-by-midi/43767 for details
