I like that it is easy to use, intuitive layout of tasks with tags/categories helps me quickly visualize my upcoming work in progress (WIP).
The ability to see at-a glance how long each task will take makes estimating much easier than doing by hand or relying only on estimates from other sources such as discussion forums which are often not very accurate! It can be difficult sometimes when some people don't follow through - they may have started but haven’t finished their assigned portion yet so its hard to add time back into your estimate if you need more hours allotted before something else starts getting done. Also there's no way within this software to adjust WIP limits once an initial limit has been set up but rather must always go over what was originally estimated unless someone manually changes them via edit button right above where we input our original numbers. This.
