No I wouldn't. For me, scanning the list is relatively time consuming. When
I'm typing I'm thinking about what I want to type next, not about what I'm
currently typing. To scan the list means that I have to stop thinking about
that, start thinking about what I'm currently typing, read and navigate the
list, then switch back to what I was originally thinking about. At my age
these are non-trivial operations.
If the contents of the list are predictable I can start taking it for granted
by using without having to think about it too much - ie. without those
expensive context switches.

I'm saying that the point is to save time.

Like I said, I'm too busy thinking about the next sentence.
Obviously it's a very personal issue. If people generally think it's a good
idea then I can add it. (It's a QScintilla thing, rather than an eric thing.)
