Imported Items in Amazing Charts is a mess. The items that I have imported are ordered chronologically, earliest on the top of each file. The lab items imported by interfaces with LabCorp or Quest are reverse chronologic order, in the same folder. If you have 100 lab items in a file, it is very unwieldy, especially when the ordering system changes for half the items. This is just sloppy.
The items that I put in can be reordered by editing the date, so someone created an ordering method that responds to user input. As Dan points out, users don't care how hard it is to fix it the right way. It doesn't make sense to leave it like this for the sixth major software version.
