Andddd: its amazing.

I just stopped by the gamemaker site for the first time in probably 4 months and this was the first thing that I saw. Something told me to look at it, and I'm glad I did. The ability to test any particles you want via this simple interface is great. Aside from needing to open all the windows in the beginning, the rest is easy to navigate. Don't have any ideas for particles or suck at making them? who cares! This program has a built it randomizer that gives you some great ideas, and sometimes great ones right out of the randomizer. I didn't take a look at many others out there, but I have used a few user-made particle creators; but this is the only one that u can:

Open it, press the "random" button, copy to clipboard, and then paste it in your game.

Maybe I just suck at guessing values to start making random particles, but this thing helped me out a ton, and if you can't find a good particle base to start with, then I say this program is for you.
