It can plot great Argand diagram (complex plane). its screen keyboard is not smart for input keywords. Editor has not undo. The Plot and Plot3D don't seem to work with \[ImaginaryI] and \[ImaginaryJ], no plot output. The Sqrt[-1] is ok.

I love Wolfram Language and I worked fluently in Mathematica on desktop. That's why I wished to be able to work, when I'm not in the office, on Wolfram Cloud. But the app is a headache for me. The connection was very unstable. Well maybe that's because I'm form outside of the U.S.. But the other major problem is that the keyboard frequently disappears without any reason, half the way when I'm inputting an expression.I cannot get the keyboard back unless I move the cursor to another cell and then back. That makes my work hundreds times slower than it should be. Please improve the mobile interface. Moreover, better hire me to work for Wolfram Research.
