Could you, please, elaborate more on that? I'm sure BBedit doesn't  
have argument hints, auto-completion etc. (features I like - but then  
that's why implemented them ;)), so I'm really curious what it can  
offer that R.app doesn't (I'm a bit surprised to hear such comparison  
with BBedit, because there are much better editors out there - but  
editors are always a matter of taste ;)). R.app *is* intended to be  
"a specialized tool" exactly for that purpose - working with R  
scripts. The only way we can figure out what users want is when they  
tell us (as every one has different workflow habits), so please share  
your thoughts with us. Even if the improvements won't necessarily  
make you switch, they can be valuable for other users.

Thanks,
Simon
