I am testing out GitHub - thesamim/TickTickSync
I moved existing TickTickSync in the .obsidian directory to TickTickSync.bak, then created another TickTickSync directory, but somehow data.json was getting read from TickTickSync.bak. When I deleted the plugin from the setttings, TickTickSync.bak got deleted. This is a bit counterintuitive to me. Does Obsidian scan all directories and then fingerprint data.json, regardless of the directory’s name?
And iCloud doesn’t let you view hidden directories, so my settings are all gone 
If you rename the manifest.json to manifest.json.bak of a plugin, then Obsidian won’t see it. You can also edit the manifest to customize plugin names and freeze a plugin at a certain version.
