Project grid

Why is the length of the project grid limited? I have been working on a pretty big thing, but the length is limited to 236 bars or 14.29 minutes, and you just can’t scroll past that point. Out of curiosity I have opened some other projects of mine. They are also limited, though at different time points. Is it some kind of setting or a stupid blunder on my part?

You can define the project’s duration from project setup. (Shift+S)

Thanks a bunch!
