Hey! New features will be added, some may come as separate mods as well.
"One sided relationships" aren't a thing in the Sims and making them is a huge pain. Redoing the core game relationship system is an even bigger pain and a one that would cause incompatibility with any other mod that exists, so that will never happen.
An animations player is planned, but it's a lot of porting and adapting work, and WonderfulWhims isn't my prioritized project as you could imagine. It will take a while, but it will come.
Thanks.
