Little Big Steps alternatives

It's a fantastic system, but I wish the lower-cost versions had more features. I'm currently using it to manage my design projects from start to finish, and it has been incredibly valuable to me. However, I won't be able to continue with the paid version and will have to switch back to the free version. It would be ideal if there was an "à la carte" option where I could select and pay for only the features I need to use, without having to pay for the entire system with features I won't use. Either way, it's an excellent and user-friendly system with great versatility.
