I made a package for toggling packages. You define a list of packages in settings, it displays the enabled or disabled statuses of those packages in the status bar (disabled packages are dimmed). Clicking the package name in the status bar toggles the package. It also defines commands to toggle the packages.
I made this because I wanted to be able to turn on and off some packages at will, namely Vim Mode and Emmet. It turns out Vim Mode doesn’t handle being disabled very well due to Vim Mode issue 298. So instead I’m experimenting with starting Vim Mode in insert mode. I haven’t encountered any issues with Emmet yet, but I also haven’t tested it much while doing real work.
Hope others find it useful!
