A few features I would like to see;
Keeping it simple, display people you've loaned equipment/tools to in tree view (similar to explorer tree) with the ability to drag items from the main list and drop onto the Loanee.
Also allow a report that shows the tools loaned out by loanee.
This would work great for DVD collections.
Also a status pulldown with option you can define. Default working, "Damaged", "broken", "In shop"
This would be great for those that have employees or family members that like to borrow objects and then break them.
We are looking at using this for our company tools tracking.
I will add this feature into version 2.3.
