What does the company do well? What I love is the scheduling aspect. You can set deadlines to a certain date, or in a range of time. The daily notifcations with what I have tasked myself for the day help me keep focus and get work done. It can be improved even more with time deadlines, so I know at what point of the day I should finish a task.
What does the company not do well? Does not have a checklist, Trello does. It seems Trello has a bit more inside tools than Slack, although they lack the scheduling aspects which is crucial. Organizing tasks into sub-groups is not perfect. When I create a task it goes to the latest sub-group instead of letting me choose. I then have to manually move the task to the correct group. It seems some features are still in beta mode, but is taking them quite long to perfect.
What do you wish you had known about the company before using? In general it serves it's porpuse, I am just being over-critical with small features that don't affect too much productivity. Checklist's woudl've been fun.
