Well actually ...
It definitely took me some fiddling to get the basics of CommonSense, especially since I've never played with PSoC Creator before. As I think DMA may have remarked - READ THE DOCUMENTATION. I really found snacksthecat's guide very helpful too!
One notable thing on my board was that key presses do pull up keys in the same row on adjacent columns - more so downstream than upstream - for example pressing a key on column five might pull up the key on column four by 6, the key on column three by 4 and the key on column two by 2. Less effect upstream with the key on the next upstream column bumping 1 or 2 and no changes above that column.
This caused me a bit of a problem in a few spots - probably due to variation in my homemade F&F - where occasionally a key press on an upstream column would would pull up an adjacent key on that row beyond the maximum value reached when pressing the adjacent key itself - making it hard to set thresholds. At first I wasn't sure if this was a wiring issue but I did see that Sangdrax noted something similar a well:

It was mainly a matter of fiddling around with the F&F disks to get around this - again I suspect that inconsistencies in the thickness, etc. of my hand cut F&F disks was largely contributing this issue.
Another big thumbs up for DMA's CommonSense from me and I know I'll be using it more in the future.
