I really suffered while using MongoDB Shell because auto completing was not there. I was very hard to type collection and database names correctly. I wished IntelliSense to get into there. I'm tough Microsoft User. Because of that I love IntelliSense a lot. ;)
And there was no any other solution to me to make done MongoDB things easier. Because available MongoDB GUI's are not that much good. I feel I'm in 90's when I'm using them. So after a month I got addicted to Shells. Not Only to mongo shell I practiced PowerShell also.
Now what I wished is arrived in a different form. It's auto completing. And it made me comfortable because feeling is same like using PowerShell. And also It suggest possible commands and functions. Isn't it awesome? It makes easier to learn MongoDB. Somehow now MongoDB is having visual differences!
