In Atom you can uninstall from the settings menu. In Sublime you can’t use package manager because the Fuse plugin is not managed by package management.
You can just delete the plugin. For instance, on OS X, you would delete
~/Library/Application Support/Sublime Text 3/Installed Packages/Fuse*.
On Windows the path is
C:\Users\<user_name>\AppData\Roaming\Sublime Text 3\Installed Packages\Fuse*
I added the post to bugs because the instructions are not in the read me or the faq. It should be listed as part of the uninstall directions or better yet added to the dashboard.
I agree! I’ve created an internal issue for us to improve this.
