Destiny Item Manager (DIM) is an incredibly useful tool that manages inventory and items in the vault without having to endure annoying trips to the Tower. It was made out of necessity for the original installment and has now been updated to support the highly anticipated sequel.
However, the functionality is fairly limited when compared to what can be done with the first game. According to its creators, the goal was to get the tool running for Destiny 2 before it was released in the United States. Hence, there was not enough time to add every single feature from the original installment.
For the time being, players can transfer items between their vault and various characters. The loadout for any character cannot be edited directly. This feature will be added soon with a future update, along with several other improvements.
Be warned though, the updated tool has stability issues. Those interested can download the application from here. The interface is optimized for mobiles and tablets, allowing players to manage their inventories in tandem to playing the game.
Destiny 2 officially released yesterday on PlayStation 4 and Xbox One. The PC version was pushed back slightly to allow the developer more time for polishing purposes. It should not be considered as a mere port since Bungie has repeatedly assured that the PC version of Destiny 2 is being built from the ground up to cater to PC-specific needs.
