I don't THINK this has been suggested before. lol
For those of us who like competitive battling, damage calculators are very helpful. There are a few on the internet already, but it's hard to find good ones, especially as most require certain applications / only work for gen 4 / are often slow or down / are tedious to use. In case people don't know what they do, you basically input the two Pokemons' stats, the move used, and any abilities, status, or conditions that affect it. It then tells you how much damage that move will do.
IMO this would be a really helpful thing to have on the site. It could go on the "Advanced" tab. I understand if this is too much trouble for you, Pokemaster, but please consider it. Thanks :3
