(after all, why would someone chatting use /echo from the editbox?).
I do this all the time to echo information for use later or to echo something that i wish to say but not at that moment.
And of corse i am sure many, including myself, use it to echo results of identifiers that you wish to modify and repeat until the code if functioning as intended. (pressing tab means typing it all again, and doing it all in script editor means window switching and save save save and echo in the code etc).
I do not think i'd personally use the feature, be i can see certain situations in which an inline /aecho (or flag equivelent) would be useful, assuming what was being echo'd had the ability to evaluate differently for each window it echo'd to.
Of corse its very easily scriptable anyway.
