For those who don't know this already, dropping a disk or folder on a BBEdit window will paste a tree catalog of it. Tabs are used but you can replace them all with spaces or lines or whatever you want in a split second. So until this program offers more than an already existing feature, I'll only give it 3 stars for the effort. Suggested feature can be to filter out certain types of files, decide how many levels to go down in a hierarchy, deciding the styles of the tree (i.e bold for folders, italics for aliases, etc...)
