Problem Statement

i tried your "/insights" feature and it focused on my last activity which was on a not very relevant project that I use once every several months. I have several terminals with Claude Code for different projects and it only focused on the last one (email sending) i've used which is a small task that i run every couples of months, i have several interesting and complex projects that I have been working on for months, which were not included.

Proposed Solution

Focus insight on projects with most activity
