GMAIL adds useful feature that roundcube SHOULD have.

Google just added feature that will check rather you've typed something similar to "ive attached blah blah" and check rather you have attached a file when you hit send.  I can't even tell you how many times I have sent emails without the attachments.

Thanks!

While I can see it being useful, how accurate is it, if we have two messages, one has the line
"in the file test.zip attached"
and the other has the line
"please file under attached single family homes"

Do we annoy the second person, or miss the warning for the first?

There would be other examples, and that's only in english...
