I've been playing the game since may, and I must admit that I love it.
But as I was playing, I was thinking that I could be very amazing to not be imposed groups of ten. As I know it could disbalance the game to have smaller groups, I was thinking that the amount of smaller groups could be restrain to a certain amounts, per fame of you company maybe ? I don't know yet, but I think it would ba awesome to have the ability to create duos or trios without having like 30 idols in your main group in order to do so.
I also was thinking that saving the formation you did would really help, cuz when you start building up a big company it is easy to get lost in your idols.
And also, I know you can see idols according to your sister groups, but it would be really nice if we could (when you do a single with your main group) have an option to only see your main group (or at least have them all put together and not having to scroll your idols for them (who would be in between the members of two differents sister groups)
