The package 'SideBarEnhancements' is not available

[antonkhvorov]

Problem:
After completing Setup steps described in README.md next error occurs:
"The package 'SideBarEnhancements' is not available"

This is happening because 'SideBarEnhancements' package was removed from Sublime package control system:
sublimehq/package_control_channel@6940c5e

Not working solutions:

1. Check original github repository instructions:
   https://github.com/titoBouzout/SideBarEnhancements/tree/st3
   Although they have "Troubleshooting install" section, the solution from there is not working

2. Another suggested solutions:

I had a similar issue too. I had to remove the line in your Preferences > Package Settings > Package Control > Settings – User file > installed_packages list since it referred to an old name of the package (with a lowercase B).
