GitKraken Glo Boards: a more productive way for developers to track tasks and issues from inside GitKraken, VS Code, Atom or a browser! Glo Boards sync in real-time with GitHub Issues, support markdown and offer lots of time-saving features for devs.
Can see kanban board status, can change status and can develop code at same place. This feature makes it soo amazing...Cons:
Not cons, but can have feature which can show estimated task and remaining effort for the task or % of remaining task.
I used Glo Boards today only but using Kraken since more than 6 months for my open-source projects. And experience is amazingPankaj Kumar has used this product for one day.
