I'm not versed in the lines of scripting and such, and there are many Blocklander's like me that would like to make cool particle effects, but don't want to fiddle with the number settings just to get in-game and see that it looks terrible, spending the rest of the day editing numbers.
It would be nice if a Particle Creator Viewer were to be made, where (either in or out of game) you could use sliders and perhaps a drop-down box to select textures and such to modify and view the particle effect in real-time.
