These tools are personal because everyones workflow, preferred keybindings, and visual organization differ. Building exactly what you want can be more useful than adapting to a general solution, and the process is valuable too. cscope looks interesting, and I like that it takes a more colorful approach. Thanks for sharing it.
hrdx was created, among other reasons, because I wanted full support for my own coding agent, zot.sh, without having to wait for a PR to be merged.
