I bought this app many years ago and I used it ocassionally for light FTP tasks. A few months ago I started doing heavy SSH and FTP related work, mostly with moving files around in a server.And I noticed that this app is terrible.It crashes all the time for no apparent reason. Ocassionally it will randomly give you "unknown error" alerts and you will be BOMBED with them (you really have to dismiss hundreds of them at a time - one by one). It's incredibly frustrating and rather than aiding me at doing my job, it makes it even more frustrating.The worst part is, the "unknown error" alerts happen entirely randomly, there is no way to reproduce the bug, so it's impossible to report it to the dev. And the crashes, for reasons unknown to me, don't show the macOS crash report dialog that you normally see. The problems are many, random, impossible to reproduce, and therefore impossible to report.I think the only hope for this app is to be rewritten from scratch. I feel nothing else can save it.If you want a toy SSH and FTP client that will be used to move one or two .txt files at most around, get this. If you actually need to be productive, don't bother with this app.
