i think when it was brought up last time the response was, we cant think of any advantages of having it as a new mod folder over having it as addon .pbo's
I think what he talks about with the addons is the abillity to make a folder for you addons under west as and example. This is a abillity that have come with the latest patch. In short it would do that you dont need to put the things under men, car, air and so on, put could create a folder called as a example SEB Vietnam units under both west and east. Advantages would be the following.
- Missions makers wont have to have a mens list (or others) where the side bar is this - thick and with 300 different men in it.
- You can cut away the creator name on the ingame model since you can keep it on the folder name. Would give better game play since you wont have units runing around with name like SEBv_Machinegunner and so on. No bad thoughts to SEB team there, just a example. Just looks better with out.
This was asked about on page 41 on this post but there where no answers. I know there earlier there where a discussion about making a folder like the resistance one, and i would think thats the you are thinking about, but with the new feature there's no need for that.
[EDIT]
After reading it again he might be thinking off the later thing
Well anyways are you considering the first part (its own unit folder) ??
