Thank you for your reply Kirk.
That's very disappointing. Is it a complex feature to implement? Are the tags perhaps already stored somewhere in a .hidden file that I could access?
Why use lo-res files for slideshow viewing? Yes it is necessary in my workflow. Speed and security are the main reasons. Laptop/projector combination are much faster with low res files and I also want to keep my hi-res, adjusted files 'off-line'. I don't want to risk messing those up during a client viewing, where I might show them some quick adjustments (B&W conversion for instance), that I'll want to do properly later.
Is this a feature you'd be willing to consider adding in the near future?
Thank you.
