MLB Manager is not designed to do more than it currently does, it is feature complete and the platform does not allow any massive changes.
We hope to be able to directly move the MLB Manager code into the current OOTP codebase one day, but this is a ton of work and we are too small of a company to be able to have done this for this release, I am sorry.
But calling the game "garbage" is just nonsense, it is very stable and a fun game, and it is just $5, which is less than a burger.
I'll close this thread now, if you have constructive feedback or bug reports, please post the in the bug report forum. We will release an update very soon and will try to fix as many reported issues as possible.
Thank you for your support!
