So there I am, using my nice speedy Visual Studio program, happily editing and running code. I want to use the new team planning features so I can pick my next task more rationally. And what I discover is that it's horrible: the isn't really a way to "plan"; I can create a work item (but is that what I want to do?), and I can write a custom query to see my work items, but what I can't do is see some boxes on the screen and move them around.
Keep in mind that I use Trello for my hobby projects; it's awesome in its simplicity. I can make new little card, and move them from column to column, and track what's going on.
So why is the expensive, heavy, full-featured Visual Studio so far behind the curve? Why doesn't it have a nice graphical interface? Where is the help for simple planning?
Answer: those are on the web, not in the full client. In order to use them, I have to leave my nice productive environment, and go to a totally different web page. And sign in. with some credentials. Which have to match the credentials I signed into Visual Studio with. But there isn't a "go to the web" button.
Never force your customers to leave your product! As soon as I have to type in a web address to go somewhere else, and sign in again, why wouldn't I just use Trello and skip the Microsoft solution entirely?
