I have now fixed (I think) the moving and editing of Includelets on the Layout tab when using an iPad or Android tablet.
You can now pick up includelets and reorder them or move them between slots (including into Trash).
You can also now double-tap them to edit the includelet parameters.
The admin pages are not great on a small screen - on a smartphone you'll struggle - though in landscape mode it's just about OK. There's more work in the pipeline to improve the admin pages for mobile devices, but for now hopefully this is enough to get by!
Thanks
Joe
