Next hardware version, make it larger
I can’t believe I’m saying this about an item of electronic equipment, but I would really prefer it if the remote were about 20% bigger and had a bit more heft (which you could get from a larger battery, solving that problem). A bigger screen would allow more text, buttons and/or larger fonts, and a larger device would also be ergonomically easier to use. You could also have a bit more space between “buttons”.
I realize I may be the only one who wants this, but I hadn’t looked at the specs closely and was surprised by how small it really is.
