I like the analysis feature that lets you select a variety of pre-defined time intervals (e.g., today, yesterday, last week, last month, etc.). I would really like to see the option "working week", similar to the option some calendar apps have to only present the working days and skip the weekend (for me, this is Monday to Friday).
This would avoid two columns in the bar chart that are most of the time empty anyway if you have a Monday to Friday job.
What constitutes a working week should be somehow configurable, as it is not Monday to Friday for all people.
