@JumpIn-Git I don't think this maintains the same behavior. Could you please provide some more background information on why we should make this change?

[JumpIn-Git]

right now, it uses these rules:

.obsidian/plugins/**/*
!.obsidian/plugins/*/
!.obsidian/plugins/*/data.json

this can be confusing for some users, and what i have made

.obsidian/plugins/*/**
!.obsidian/plugins/*/data.json

does the same and should make some more sense.

here are some git commands to prove its working:

obs on  main [✘!] 
❯ git rm --cached -r .obsidian/
rm '.obsidian/app.json'
rm '.obsidian/appearance.json'
rm '.obsidian/community-plugins.json'
rm '.obsidian/core-plugins.json'
rm '.obsidian/graph.json'
rm '.obsidian/plugins/obsidian-git/data.json'
rm '.obsidian/plugins/obsidian-style-settings/data.json'
rm '.obsidian/themes/Catppuccin/manifest.json'
rm '.obsidian/themes/Catppuccin/theme.css'
obs on  main [✘!?] 
❯ git add .
