Yeah! For one thing, tylr makes it possible to make sub- and cross-structural selections, which isn't possible in other structure editors. Try typing `2 + 3 * 4` in MPS and selecting `* 4` or even `2 + 3`—you can't because they don't correspond to abstract syntactic terms. tylr understands these sorts of arbitrary range selections and makes sure you manipulate them in reasonable ways (eg see https://twitter.com/dm_0ney/status/1414742962442014720?s=20).
