Better keyboard support comes in next version. Do you mind telling me why do you switch between tasks every 6 minutes?
I quite often fix bugs in 2 or 3 minutes, or even less - on separate tasks/projects.
However the minimum time allotment for these things (billing) is 6 minutes. All time tracking (per contract) is rounded up to the next 6-minute (1/10th of an hour) interval.
What kind of bugs are those that could be fixed in 2 minutes?
Different strokes for different folks - just because you don't work that way, shouldn't preclude thinking about folks who do. The world is a big use case.
