90% of the time, we don't need to edit reports. Now that relative dates and similar settings exist, it is no longer necessary to review settings every time you run a report.
Clicking the report name is one click. Clicking the three-dot menu and then selecting “Run” is two clicks.
It is less intuitive to use the three-dot menu instead of just clicking the report name, especially for regular users who just need to run reports instead of editing before running.
Finally: loading the report edit window is frustratingly slow, with no way to opt-out if you click the report name by accident.
