I’m generally hesitant to install anything that can’t be easily installed and uninstalled from the command line. Typically for my GUI apps I use Homebrew Cask. Consider adding a Cask for TotalFinder.
# don't you want this awesomeness?
brew install totalfinder
The only problem is that this would be another thing for me to maintain and I have too many projects under my belt already. Anyway I will consider it depending how hard would be to automate current installer. Thanks for the suggestion.
