HYPERT This app hasn't been updated in a while, and Ranchero just answered my query via email - they "don't have plans to update Big Cat any time soon. "
That's too bad. This is promising, but does suffer from a lack of hierarchical folders and support for aliases.
Still, this is easier than having to create Platypus wrappers for every common shell/terminal command you want to do, but you can read their website to see how many people have been requesting support for aliases. It would make this even more useful...
