Just like how it was back in Arma 2, please make it so we can remove and add DLCs if we want them or not.
I doubt anyone wants to have 9 GBs of content in his/her PC that is not accessible.
I believe in the DLCs tab, we should have the option to add and remove DLCs, so, for example, if we didn't buy a DLC, we can just remove it. If we want to join a server that uses that removed DLC, we can just install it back.
This would be very useful for users who have limited amount of space on their PC, but would also increase loading times.
