Yes - much better. Though if you're deciding on the color based on iter/text at that
point, it gets it a line out. Moving it to the following if block gets it right
though. ie...
view layout [
t: text-list "aaa" "bbb" "ccc" with [
text-pane: func [face id][
if pair? id [return 1 + second id / iter/size]
iter/offset: iter/old-offset: id - 1 * iter/size * 0x1
if iter/offset/y + iter/size/y > size/y [return none]
cnt: id: id + sn
if iter/text: pick data id [
;**** EXTRA CODE
iter/font/color: either iter/text = "bbb" [255.0.0][0.0.255]
;****
lines: at data id
iter
]
]
]
]
