Rich designed it with trigger IO pins to be able to easily chain them. While the UI doesn't support managing multiple Flea-Scopes at once, you can just open the UI multiple times, which does seem like a reasonable option to me. As as others have pointed out before, there's just no alternatives in this form factor. The scope is tiny, and for what it is it packs quite a punch. 3.3V and 5V are standard logic levels which will suffice for quite a lot of basic probing. Being made for students, it does likely everything that would be required of it in an educational environment. How well this pans out in real-life we'll see soon. Granted that with enough money and space at hand there are much better options out there.
