I have been using Dopus for a year now, previously having been a user of PowerDesk Pro for many years. The more recent versions of PowerDesk were getting buggy and not as well supported and in fact over the years I had a number of quirks to deal with. I decided to make the switch after having done some serious web searching and study of the options. I am thrilled! Although I don't begin to plumb the depths of what Dopus can offer it has already provided me some new tools and others I hope to have time to implement in the future.
It has been bug free for my purposes, and whenever I needed help on understanding something the forums have been very accommodating.
So thank you and happy new year.
