It would be nice on the SMS editor to see the number of segments the text is using and the encoding type, say GSM-7 UCS-2 so you can tell if it is going to cost you more than you think. Since text messages are charged based on the number of segments, something that is 240 characters may actually end up costing you 4 segments if it gets UCS-2 encoded because of a single quote or comma. See https://twiliodeved.github.io/message-segment-calculator/ for some ideas
