Important Note

This plugin was created as a temporary convenience tool until official support for Hex View and Edit features is implemented in Caido. Once the related issue is resolved (see caido/caido#29), this plugin will likely become unnecessary.

Until then, feel free to use it to improve your workflow!

Special Thanks

To Michael(@dyrandy), whose quiet persistence finally won. This plugin’s here because you asked nicely.. a lot. 😉
