Cons
Con No Google calendar support
Con Not made for app users
If you come to any professional or console software, expecting it to just behave like your Windows GUI apps, … you’re gonna have a bad time.
You will need to know what you want, and actually tell the program so, by configuring it. So that then, it will fit you like a glove instead, of you having to fit into a dumbest common denominator mold. Like all professional software.
Con No built-in help
The “help” function only tells you that you can use help on the program’s functions. But not what functions there are! How can you know what to ask for when you don’t know what there is? It’s like a text adventure game or Family Feud all over again.
Con Keybindings also used by certain graphical terminals
The keybindings of either program have to be changed in that (rare) case.
