I have a suggestion that I would love to see in LMMS. It would be nice to have the ability to copy a whole segment with multiple instruments and paste them elsewhere in the Song Editor (similar to that of FL studio). I would very much appreciate it as copying individual instruments can be very tiring sometimes. Thank you

I want to know if you are aware of the 'clone-track' feature in cog-wheel-context-munu?
That is a fast and efficient way to duplicate a track
