I usually avoid funding any of my decor until all the decor in the room is placed, because the collision makes placement a nightmare once items have been funded (I have one item in my trading room that I CAN'T fund because the hit box is larger than the item's interact range).
Can we either eliminate the collision for item placement in free placement without surface snapping, or (probably "easier") have a "fund all" for single rooms? I think a fund all was added dojo-wide, but it doesn't fix collision issues for rooms that are in progress.
