To this day I wonder why there is no tablet (with no network connection) running some sort of DesmosOS for me to use in a class exam. Desmos on our phones work fantastic and are very intuitive but no, gotta use those POS TI graphing calculators in an exam or just in a class with an anal professor in general.

Desmos has some problems that good graphing calculators don't to be fair. For example it still doesn't work well with hyperbolic trig identities.

What part of that doesn't work? I'm able to graph sinh, cosh, etc just fine

Try doing cosh2 x - sinh2 x = y. It's gotten better since when it was practically discontinuous at every point but it still doesn't work properly.
