Hello! I hope you are well.
Firstly, thanks a lot for maintaining OpenInv. I've been using it since 2014 and I always recommend it to others.

This is a very simple issue.

In the following example, Oaksworth is the command issuer and fvsparkles is the target.

When Oaksworth issues /openinv fvsparkles, the GUI title will be "Oaksworth's Inventory" instead of "fvsparkles's Inventory":

The same thing happens with /openender fvsparkles:

The intended behavior would be to display the target's name on inventories and ender chests.

Thanks in advance! :)
