Ability Categorization

I am just wondering if setting a spell as item or hero or changing its race has any effect on how it behaves in-game. Because I am changing those attributes around for the purpose of organizing my custom abilities in the object editor and I hope there are no side effects.

I do realize that making an ability a hero one enables it to be added to a hero's Hero Abilities list and therefore be researched and all. But is there any other differences? If I add an ability with a trigger are they all the same?

Race and catagory are just for show.

As for abilities, I think so, when adding them with triggers, hero and unit abilities work the same.

Thanks for the reassurance.

EDIT: Actually I discovered one thing. The tooltips for the abilties disappear from the editor when you make them item abilities. However they still show up in game.

they don"t dissapear, they are moved to item section of the abilties...
