First there isn't a whole lot to see anyway, the only things activated by standard are hp info on target, dps on all targets in memory (this might be a little buggy, if something gets weird, alt + shift + d resets dps values), a radar (integrated to the mini map, zoom level 1) and self hp percent. All other features can be turned on and off by using combos with alt/ctrl + keys. Help window to be opened with alt + h.
Keep in mind that this is different from the esp of plox (and probably yours, too), as it's purpose is giving more accurate information instead of enhancing usability to create advantages. The only thing that might be a little unfair is the floates that can be configured to show enemies (or allies, for that matter) on 7000 range with hp, profession and more.
