I've noticed that sometimes I see something interesting here that I need to read or think about, but coming back to it, to re-read or reply, doesn't happen 'cos it's lost by then.
But NOW! I've discovered (after all these years at work and home!) the "Save for Later" bookmarking system here! That little ribbon icon puts the individual post into "Later", top-right.
Apologies if I'm the last one to find it.
