Allow selecting the time frame displayed in the menu bar

[abd3lraouf]

Problem

Currently, the menu bar display is hard-coded to show usage for the last 5 hours, with no way to change it.

Use Case

Users want to track usage over different periods — e.g. 5 hours, this week— directly from the menu bar

Proposed Solution

• Add a setting to choose the time frame shown in the menu bar (e.g. Last 5 hours, This week)
• The selected time frame should update the menu bar label/value in real time
• The preference should persist across restarts

Alternatives Considered

No response

Additional Context

The menu bar is fixed to a 5-hour window. There is no option to switch to weekly or any other time frame.
