We are experimenting with Github Flow, as defined here.In short, every change starts off as a well-named branch off of master. When it's done, you open a PR for that branch, it gets reviewed, and then gets merged into master. It's a very simple workflow.However, we have run into this a couple of times: I develop feature X, and open a PR for it. While I'm waiting for the PR for X to be reviewed, I want to start work on another feature Y, but I need the code from PR X.  Should I just start a branch from the feature X branch, or if I've already started feature Y, just merge feature X into the feature Y branch? It seems so, but I wanted to check with other teams that are following this model to see how they handled multiple PRs and features that are dependent upon each other.
When using Github Flow, what if my next feature depends on code from a pending Pull Request?
