Is this the same issue as the one reported in this thread? https://world.episerver.com/forum/developer-forum/-Episerver-75-CMS/Thread-Container/2017/12/episerver-cms---shortcut-sort-order-is-off-and-missing-search-field/
Yes that is actually the same issiue as the one you mentioned.
In the newer versions of cms the shortcut dialog no longer show the same site tree as the on the left hand side. And this seems to be because the dialog now shows all content and not only pages therefore the sort order is by type and then alphabetical.
Are you planning on doing a fix for this so that the shortcut dialog shows the tree according to the orignal structure?
