The problem is that you are seemingly doing all this in an editor instead of through the Panel. The Panel would automatically create a meta data file for you and you could sort files in the Panel and a sorting number would automatically be put into this meta data file. You could then sort by this sorting number.
Yes, it needs some work to set up, so not too much stuff at the same time. But once you get it, you will love the flexibility (thinking about your clients, but I think you have already seen this in action, given that you worked with a dev on a Kirby project?).
Urm, I’ve just opened the Panel and I can’t even see my child case study pages. I’m loosing the will to carry on…
I haven’t worked with a dev on a Kirby project. I dabbled with Kirby a few months ago, but gave up. I really like the look of Kirby and may at some point have enquired about bringing in a Kirby expert to work with me on a project
