invalid package name

When I try to install via the URL https://github.com/timburgess/brackets-ftp-sync/archive/master.zip it says "Installation Failed. FTP-sync is an invalid package name".

If I drag and drop the zip file where it says to, it says "Install/update aborted due to the following errors: path/to/file/filename.zip Unknown internal error"

brackets is useless if I can't connect to my server via FTP. I'll just continue using codeanywehre if I have to but everybody raves about brackets and I wanted to try it

As you pointed out the installation fails due to "Unknown installation error ["BAD_PACKAGE_NAME", "FTP-Sync"]"

Works just fine here..
