This helps me out a lot. It saves me the trouble. It's neat to have, but since it can't edit natures, you MAY want to have pokemon with bunches of different natures, (like have 8 bidoofs with different desired natures, so you copy the bidoof, then edit as wanted like evs ivs moves species names blah...) so you could have more then one nature, with out having to use POKESAV on the computer.
It's n00bzorz friendly (ALWAYS A PLUS ), it's very pleasant to look at, and it can have music. If this were a rating thread, I'd give it 5/5.
It has a lot... I mean A LOT of room for improvement, but it's fine the way it is. Personally if it had nature editing, and color alteration (normal to shiny, or shiny to normal) it would be perfect.
