First of all let me say that the feature to rearrange items was taken out by choice of ERPNext developers. It was a feature that existed before. See Users will not be able to re-arrange standard fields
The reasons check out and I agree to them, but since custom fields are not necessarily placed where you place them it creates an issue.
I am completely aware that I could potentially fix this myself. I have created modules for our CRM (Zurmo) as well so this shouldn’t be a problem. However, I know that future updates might break my fix or that it might take ages before my pull-request with the fix will be incorporated into the next stable release. Another thing is that my time is very limited so my patching will take a lot longer than that of official developers that sit on the code constantly. However seeing as this has dragged on for more than a month now I should’ve just patched it myself and not cared about creating accounts to notify anyone.
I find your answer “just do it yourself” a bit weird though. If that is the go-to solution for bugs or issues, I am confused why we have to report bugs here and in the github issue list if no one cares about them anyway? It doesn’t really shine a good light on your PR or issue management.
