Here’s another random UI tip for you, this one discovered by McCabe Maxsted:
Drag and drop an inventory item into the IM window to send it to the person you’re IMing with. You don’t need to open their profile window! (This doesn’t work for group IMs, though.)
The next version of Imprudence will have a little reminder note in the IM window, but you can do this with any SL viewer right now!
The more you know!
