That's it. Works as you said. Thanks for helping me out.
'ncurses' options is best IMHO. It's good to have those alternative, and
drop-down control is interesting, but this is it - in front of you in easy
accessible table and now I can set it in shape (in rows for now) that I
please :)


If auto-complete functions were sorted alphabetically by row we would have
seen full 3 columns with 24 functions, while currently we see just 2 items
in 3rd column (in posted qtconsole example). For me it's easier to read
alphabetically sorted table by row in this case when table is clipped


No, because to do so the 3 colums would have been more than 80 characters

I don't quite understand what you saying here.
I expect that colomnizer calculates whole table before it show "selected"
part of it, but won't column width depend on context? In a manner that if
some time sorted by row gives wider columns the other time it would be
opposite?
Or are you saying that probability of wider columns is less when there are
less items shown (as in example that 3rd column isn't populated when sorted
by column)? I guess not, but can't get the meaning of this


as that's how cursor TAB interaction has been made.

OK :D
I really wanted to post that couple of times, and while reading Thomas'
reply got carried
