This is fantastic. You’re right, brilliant in conjunction with the Note Properties tool. Thanks for this.
A couple more along similar lines that can be helpful with beats are Groove Control as a macro for the renoise master groove controls. Can be useful to experiment with groove/ swing settings. You also get a readout so you can apply the values manually after experimenting. I find after adding some swing with hihat / percussion offsets it can work quite well to add a few percent swing on the renoise global settings:

Also Velocity Pan Delay Automation gives access to the note properties via the automation lane:

nisanmol also has a groove tool here that may be of interest too which adds the values directly into the pattern instead:

along with dblues tool that gives a graphical representation of renoise groove values:
