Agro Suggestions in keeping the spirit of this projects are appreciated, thanks! It’s good to know of options that can make the light smaller. Beam profile is relevant too, are there beamshots?
I actually quite like the beam profile from the C01S, as described in my first impressions .
chenko Ample knurling requested. 
I have expressed the same wishes to Sofirn about the battery too.
nowonmai First Group has been stated to start low, and other groups/modes will be added only if they do not compromise simplicity, cost, and size. Your wishes are right in line with the project goals.
tacocowboy I have also requested a clear/raw anodized option. I do hope they offer this!
