I have a big suggestion as you can see in the image I recently edit.
there is a problem for anyone with a lots of tasks and lists, even more a problem if you do a view of everything, we have to scroll down a lot. here comes the option of reducing dead areas.
And if you have a widescreen - why not move things to the side?
The situation right now is that each task looks like a long (and boring) white line
Think about this, at least give us the option (as settings mode) to choose between the two modes (The current design, and the design I suggest)
