I know it's not that big of an issue, but I think a nice convenience change could be having a command telling you where your store is located. I'm shamed to admit that here's been more than one time where I've had to go to my store and totally forgot where it was located. Sometimes, after heading to bed for the night and totally forgeting my spot, I've had to walk through 10+ FM rooms just to find it. This is obviously just a user-error on my part, but I don't think having a command like this in the game would allow anyone to have an advantage over someone in GMS.
If it's a simple update that won't take long, I'm up for it and fully support. If it require the GMsa lot of coding and mixing around, I'm okay without it.
