Context

I use the personal timetracking widget to check that my timesheet is accurate week by week. I do it once a month.

Here is what I do: I select the timeperiod of a week (monday to sunday), check that timesheet is ok, then select the timeperiod of the next week, and so on until the whole month is checked.

Problem

Selecting a timeperiod for a week four time in a row is cumbersome.

Current selector of predefined period (last week, last month, …) does not help.

Expecting behavior

Since I am seeing a period of time, there is a high chance that I would like to switch to the previous or next period (same duration). The widget should allow me to do that in the fewest click possible.
