I often have multiple items freshly moved / pasted to a grid and need to put them under different top level items quickly (via drag and drop with the mouse).

With the recent effeciency increase for drag and drop (easy to drop under parent even when the subtree is folded, plus items are dropped at the top of the subtree rather than at the bottom), this has already become much more convenient.

However, the fact that the subtrees remain expanded after the drop mostly sabotages this mode of operation and makes refiling several items in succession uncomfortable as a lot of scrolling becomes necessary due to the subtrees staying expanded after items are dropped in them.

As a solution, I would suggest a toggle-able 'refile mode', which, when active, would stop the subtrees from expanding after a drop (or would fold them again automatically after a couple of hundred milliseconds of visual confirmation that the item arrived in the right spot). When inactive, IQ would behave as normal, with the subtrees staying permanently expanded after a drop.

Cheers!
