Dreaming of the next Pi's features...

Its already there.

You can safely power it off when the only LED still on is a steady red.

Well it's even easier to add a WiFi dongle, but that didn't stop them adding built in WiFi!

Seriously, I know how to wire a few LEDs in series with resistors, but by the time you've got it connected up it's either a piece of veroboard on the end of an inconvenient trailing wire, or something built like a fragile Christmas tree on top of a 2x3 header. Or there are solutions like but that's expensive and overkill for just adding an LED or two.

Or is there a cunning construction technique I've not thought of?

Yes, with recent firmware on Raspbian (since about 6 months? not sure). Just before power down the green LED blinks 10 or 11 times then goes off, leaving the red one.

Recent? I see the same. Mine is from August five years ago and has only 256 Mb memory Has I bought it two months later, I would have had a half Gb.

Firmware gets updated with normal software updates, once in a while. Check with "uname -a" and/or "vcgencmd version". Either will display a date.

How can a firmware update make my memory bigger?

Thank you for this information.

Why do you think anyone suggested that it would?

A. Dumas wrote about firmware. I can't see a relation to what I wrote.

you were original referring to the Red led illuminating for safe shut-down

this feature would have been added as part of a firmware update.

Indeed.
