Some further thoughts and a more positive spin based on watching the (breathtakingly fast) what's new video...
Several of the features regarding merging, synchronisation, metadata handling are available now (not in the 'DOpus 12 light' release from 2017 I was using).
I will gladly pay my money for the pro version and look forward to using the latest version with my own cat videos.
(Still consider the features as too configurable and not easily 'discoverable' particularly for 'normal' rather than 'tech' users)
I also recognise how amazingly talented the small DOpus12 team are. They've implemented something that Microsoft should have done....
e.g. those of attribute changer https://www.petges.lu/ modifies metadata between source and destination without changing the underlying identical files.
e.g. personally find winmerge and winscp a simpler solution to some aspects of comparison and synchronisation (but need setup)
Overall I do use Opus regularly but largely to just get a count of the contents of a directory (avoiding a manual file propperties right click on the folder.)
I appreciate the software development costs, but £25 for a single node locked license is steep. I'd like to see that extended to at least a couple of PCs + a laptop as many advanced users (who can regex :) ) are likely to have at least a couple of PCs round the house in these work from home days.
Overall 3.5 out of five - undeniably powerful but interface is too fussy
An extension of the zig ideas is making self contained portable and very small binaries that run everywhere from bare metal to any OS using a cross platform libc and configuring GCC or clang appropriately.
