I'm finding with 6.8.0 that the App Structure panel isn't updating cleanly with changes made in the properties panel or the code compared with what felt like a very smooth connection between those areas with 3.9.7.
Is there an option I need to set somewhere or a mode I need to be working in to make this better?
I'd highly recommend installing the Beta @Antony. Hear how you feel about the updates to the UI etc. See if there is an improvement for you over 6.8 with the issue you have outlined above. No need to update any files to make use of Beta 7. Am sure your feedback would be considered helpful, and you may find the issue is now resolved? Your feedback on the previous Beta was invaluable and am sure it would be more than welcome with Beta 7 too.
