I finally decided to finish the loadout feature that I've been working on.
On the inventory interface, you'll have access to buttons at the bottom left corner which you can click to save, delete or load a loadout. By default, you get 2 loadout slots for free and can purchase up to 8 extra for a total of 10 slots. The loadouts are shared across all your characters. You can also assign these loadouts a custom title to make it easier for you to locate the loadout that you would like to load.
I am also working on a page at fgunz.net that will allow you to import loadouts of other people into your account, including a counter of how many times your loadout has been imported by other people.
Below are some screenshots of what it looks like right now although it will most likely slightly change before it is put live in the upcoming weeks.
