Disk Order is/was a fast and sleek two-panel file manager for Mac. However some bugs were never fixed. Releases just stopped, and the company site later disappeared. The primary alternative, Forklift, is just too slow in the version three. Double Commander works but doesn't integrate well with native OS features. (Total Commander remains a distant ideal on non-Windows platforms. Boy do I miss its speed and comfort.) Hyperswitch the cmd-tab enhancement is still very usable and is updated, however the updates seem to be limited to resetting the ‘beta’ time limit. Not that it needs new features, but I think it does have at least one bug. I'm also baffled by the author's release model (the time-limited but repeatedly prolonged ‘beta’) and irked that among the couple dozen apps on this topic there aren't good open-source ones without some dubious features. Since Hyperswitch is fully freeware, why not make it open-source so others could fix problems they run into? I think there were other ones, but can't remember them right now. Basically, if an app doesn't bring in plenty of money, why not at least let people make something better of it.
