To make this a tide item, just follow https://github.com/IlanCosman/tide/wiki/Custom-items-(prompt-segments). But here are the steps:

• funcsave or move _tide_item_jj.fish into .config/fish/functions
• Add the item to the prompt with set --append tide_right_prompt_items jj (tide_left_prompt_items to add it to the left side)

Thank you for sharing this!

This works really well, thank you!
