I appreciate the topic of customising the panel has been well and truly covered, and that only the css can be changed. However I was just wondering why that decision was made (sure there’s a good reason), if anyone has had any success and if that will change in the future. I’ve had a couple of cases where I really could have done with editing the actual markup a bit beyond what css will allow, and I’ve taken a nose at the app.js file and it seems pretty intense!
Revisiting this one again, and thanks for your help @texnixe. Unfortunately I’m a bit lost so hoping you can help provide a re-steer. In the example above, where is that code going? I’ve read up on creating plugins but as soon as I get involved in the panel here things start to seem much more involved: https://getkirby.com/docs/guide/plugins/plugin-setup-panel
