Here's a fun tip for all you people like me who like to play legacy, but don't have a good enough graphics card to use a custom client, and thus must use the crappy default one. NOTE! This is a test to see if this works for other people. I'm not 100% sure it will.
Step one: Log into your game, and enter fullscreen.
Step two: Put your system into sleep mode. I personally have a laptop, so i just close and re-open the lid.
And done! Now your screen is in the top-right, and you have room for all your other UI stuff like the equipment and inventory, without getting in the way!
Please make sure to reply if it works for you or not. Also, sorry if this is well known or something like that.
