Is this a design choice?
"This is evolution, not intelligent design" ;) I.e. this was done for particular purpose, i.e completing To: field -- there choosing something that is not offered can be written in the To: field directly (or the completion can be edited afterwards)... Also in case of selecting address one can go back to the 'From:' field and edit that... > I think I would like to be able to type in the buffer it shows, > e.g. page down to page through lots of addresses, maybe ctrl-s for > searching.

Narrowing would be simple but expanding when deleting (especially when deleting past initial search) is something... thought expand so fast that...

I'm not familiar with this "history" feature, so currently yes. But depending how history works it might be applicable to add in a form or another. Also, if there is use for this outside of my current use case then how to implement all desired features are something to think of. I've so far thought some more args or layering or something to make this more generic. > > Best wishes > > Mark Thanks for interest Tomi
