This may be more of a a request for an entirely new product, but one that would be based upon much of the feature set of DOpus.
The Windows folder & file requester dialogs, varied as they have been over the years, have continued to be stagnant in terms of improvements. Perhaps a replacement for them (as configurable as DOpus is) could be made. Of course, it would have to replace the Windows 11 versions, back to the old System32 Win dialog requesters that can't be expanded to when showing folder listings. Some of those old dialogs don't even let you use UNC file paths. Something standardized, configurable with persistent settings (like where to appear on screen and its size) would be very welcome.
