* The UI looks very confused. It seems to use material design elements very inconsistently, in particular on the landing "what do you want to do today" form which looks out of place.<p>* The task counter in seconds becomes useless after long amounts of time. Maybe put a timer in mm:ss?<p>* What does the "completed" switch in the upper right do? Doesn't seem to change anything.<p>* It would be nice to be able to switch a "done" task back into "undone" in case you realize there's more to do about it.<p>* The checkbox is not aligned to the "start" button properly. I know it seems like nitpicking but we are hackers with OCD and we can't stand this kind of things :)
