You are very precise... so I will do too. I didn't say *you* asked for 
features (did I?). Nevertheless you was talking about features...

Are you expecting I say "you"? No. I don't know who you are, and even if 
I don't agree with you, I can not say you are not a real programmer.
But BEWARE! In some future, perhaps I will do! Even at night! :-)

No, again it was a general talking. But are you sure you fully 
understand Columnview?
I noticed that, for example, checkboxes lack the Autosize property. It 
would make sense that every control like labels, textboxes, checkboxes 
and data controls had a set of common properties. But for this kind of 
things gambas relies on either QT or GTK, and sometimes you find limits 
in them. Be prepared...
I tried (and actually succeded) to write a file manager in gambas. But I 
faced all kind of problems, and I had to rewrite DirTreeView and 
DirFileView (or whatever is named). Do it it you too, then you'll better 
understand what I am trying to say. The more a component has 
functionalities, the more you will find they are not what you want.

Hey guy, keep it cool.
