I like to think of a pedalboard as a self-contained, portable version of a studio. Studios are always works in progress for the same damn reason:
They keep coming out with juicy new
stuff.
I put my current pedalboard together in 2018. I hoped I wouldn't have to mess with it for a long time, and it has been largely the same, but I've made a few small changes.
I planned to ditch a separate tuner, and initially did that using the tuner on the H9. However, I found it a pain to use, so I added a tuner with a better display. Luckily I had room for it.
My overdrive was a dual pedal Pettydrive 2. I only used the Chime part. So I gave it to my son (he still tours with it) and got the single Chime pedal and their Edge low gain pedal that I like very much. Those are the only changes I've made, but still more than I planned on.
I use the Mission Engineering expression pedal made to work with the H9s. But for one project I needed a volume pedal and got the Xotic (probably the same one you have). Unfortunately, I only planned on the expression pedal when I got the Schmidt, would need to add their two-rocker-pedal upper shelf and redo the board.
Seems like a lot of work I'm not eager to do at the moment.
At some point I may add a second, smaller Schmidt for additional pedals. I'd very much like to be done and just use what I already have.
But as I said,
they just keep coming out with juicy new stuff!
Change is inexorable.
