Grouping by directories probably isn't wise, since you don't necessarily have to use the structure in the example. You could have a wealth of top-level directories and end up with the same problem. Alternatively, you could be using top-level directories as packages in the first place. And, further, you could be using some combination of the two!

However, I do like two other parts of this:

• Being able to select all logs: At times, this is just more convenient, for situations where you want to watch for the timing of something, for instance
• Some way of creating a deterministic order: It's possible for us to create a specific order, but the problem is, order with what? We've discussed using the task graph or going alphabetical, but both of those options come with their gaps. Would be interested to hear your thoughts.
