• Updates `ivy--old-cands‘ with the result of counsel-jq (Fixes Gives wrong results with ivy-occur #7)
• Configurable buffer name and binary
• use display-buffer instead of switch-to-buffer

Hey @munen, did you get the time to look at this?

Hello @munen, reminder for this. Let me know in case you want some different implementation.

Hi @Gleek

Looks good to me, great work!

Good thinking for also making the counsel-jq-command configurable. This makes it easy to switch to yq instead of jq to work on json and yml files! I'll add some documentation for that.

Thank you, again and apologies for the latency on getting back to you. The last two months have been quite challenging.

🙏 🙇
