First off all, hats off for this great idea and article. Really inspiring!
The one thing that instantly reminded me that I sent an idea to IBM (https://ideas.ibm.com/ideas/PAOC-I-1293) was that it would be really nice if we were able to attach the possibility to run TI-processes directly from cube cells - just like the drillthrough but with more precise control.
