Just a couple of suggestions for the PCB.
Move the 3 resistors circled in red farther away from the solder pads they cross, similar to the same resistor at the top right.
See the suggested layout for the LED and resistor placement change made in this mock-up.

Thx Dave for taking care.
Done as you proposed, and added that "if you want to, you can add a trim pot to R8 / R27 and, after fiddling out the correct value, you may replace it with a fixed R; if you don't care at all, just solder those yellow jumpers"-feature:

An externally hosted image should be here but it was not working when we last tested it.

Hi Holger,
Nice work so far. Of course we have to have the "Steeno" multi-cap option for C1, that was recently added.
Could we see a version without the silk screen or components in place? It would be nice to see the gaps between the traces and pads.
One other thought is to move the V+ slightly to the left for more clearance.

Dave,
here ya go: http://www.hb001.de/alephjpcbbottom_rc8.pdf
Drill sizes minmized, easier for homemade pcbs.

Clearance is above 8 mil everywhere, this is what most board houses ask.
Not a good idea. Need some space for the pcb mounting studs around the corner holes. Moving the pad to the left might cause a short between V+ and the grounded chassis.
