A user, maybe, thou they've never posted here promoting Flow. To which I would gloat, its an awesome tool.
Furthermore the Dopus integration could be more robust. it only makes sure to open folder with DO over explorer. I believe a handful of other file manager are also supported.
It would be amazing if they took the integrations a step further to include our Favorites, Layouts, and Open Locations such as jnllnd has done with Quick Access Popup (aka Folders Popup) working with Directory Opus.
There are over 100 plugins written for Flow. Alas I'm not great coding or I try to do it myself.
