Yes - it certainly is weaker than the desktop (classic) LR, but it matches the mobile app quite well (and syncs to the desktop). This is the secret sauce. I can do simple smartphone pics, edit them and they will merge with main catalog. I can further refine on desktop (or vice versa) and it all syncs, and my originals stay with the desktop (the further backed up via whatever mechanism I want).

I applaud the idea of interoperability for the FOSS applications, but pulling this particular feat (the use case I describe above) off is non-trivial and requires enterprise level architecture and coordination. It's a very different type of challenge than making a great non-destructive editor with local organization. I don't mind paying for this sort of thing, but I wish it was officially offered in Linux-land. Wine is great (if it works) but it injects a substantial risk of breaking as applications get updated.

Would love to run Linux everywhere, but there needs to be official support from some key companies for that to happen. It's a difficult thing for them to justify (rightly or wrongly). I don't think open-source alone will solve things. Unfortunately...

Oh well - I got off topic here. But I was toying with trying another switch to Linux just this weekend and this is front of mind...
