My main surprise was in its responsiveness considering the 'virtual' setup through Parallels. I am very impressed with its capabilities and excellent documentation.

It has image versioning and image stacking. Now, I have no Catalog sets nor Collections and little I have tried, the program is VERY powerful and deep (the software has Attributes, Collections, and Categories ! So far I know I just scratched the surface but it looks like I found a new home for my hobby.- there will be a learning curve, but it can be done in 'steps'. (just picked my 2016 folder) and the whole process took give and take 4 hours. Well, I am on a MacBook Pro and installed Parallels desktop, Windows10, and iMatch2018 (all on trial for now) and ingested 31372 images (after initial smaller testing sizes of course) - NEF, tiff, jpg, ARW, ORF, iPhone and iPad images. Certainly easier than doing it manually but a very long process. Also I re-ran the Catalog Sets to Collections script for Photosupreme and while it is now doing it automatically it's been running for two days non-stop and has still only done 3% of a 60,000 image catalogue.
