Yeah, well said - I would think a visual helper or delay would help prevent accidentally dropping something in (a little like the Mac finder's pop up folders)
Ive been giving this some more thought, the number of teachers who have come up to me to ask how to group their resources is quite astounding. We have over 200 teachers and I think about 20 of them have asked about it. Particularly teachers who have placed a large number of links on their page.
They dont want to create a new Section, they simply want to be able to group their resources in something similar to a Folder. And they dont like the look of the Flexible Sections format at present - it also isn't compatible with Sharing Cart.
If Moodle doesnt want to change the Folder resource - as in keep it only for Files that's okay.
But perhaps creating a Collection resource which can be used to contain any group of Resources or Activities. I think it would be a very simple addition to core functionality. The Collection could either open on the page dynamically or go to its own page.
If users could drag their Resources and Activities into the Collection, that would great. It could also be a very easy way to move multiple resources around the page.
When I have time, I might create a Moodle Tracker for this.
