[pawamoy]

• bash history: write a function
• zsh history: write a function
• bashhub: bh -n 10000 > last-10k.log then parse (https://github.com/rcaloras/bashhub-client/issues/52 😀 )

Boost priority

• Boost priority in our backlog through Polar.sh. Higher pledge, higher priority.
• Minimum pledge by user/organization is $5, minimum amount for boost is $30.
• View all issues with pledges.
• We receive the funds once the issue is completed and confirmed by you.
• Features with the insiders label are released to sponsors first, and tied to a funding goal.
