So I went back and played around with LW to see what all has changed since I last looked at it, and I finally remembered what the fatal "flaw" was for me previously workflow-wise. The reason I've come to always rely so heavily on my bookmarking links approach is because it's just a couple dead simple clicks, and more importantly it works identically everywhere - desktop, mobile, etc. doesn't matter. The workflow is 100% identical everywhere with no additional apps or anything extra required. Having to open a PWA (or even a separate app if it were native) when I'm on my phone just to save a link is a few more clicks and I didn't want to have to change up my workflow based on what device I happened to be on at the time I found something.
However, since I last trialed LW I have made a real hard personal push to switch over to Firefox as my dedicated browser, and while there's a few things I don't like as much the ability to run extensions even on mobile is positively amazing. The LW one appears to not be compatible officially, but with a little persuasion appears to work just fine...and if that continues working then I could totally see myself switching over to this! Still poking and prodding and trialing it out, but fingers crossed!
This is a pretty accurate summary from my experience. The only thing I'd add is that (from what I've read at least) some form of 'smart' album functionality is high on the priority list and shouldn't be too much further down the line. It may be a more advanced customizable logic type of solution (again from what I've read) but the functionality of putting person(s) 'x' into album(s) 'y' (or similar) should be achievable.
