I’m 
'ing this because floating ideas like this is absolutely perfect for the forum and others may be inspired to build something like @zzq’s Altbee — the alternative Beeminder web interface
That said, 
at the idea of Beeminder itself going down this 
! I’m especially averse to treating customization like that as a revenue source.
But again, very sincere appreciation for floating things like this and I’m eager to see others’ reactions!
