I just hate to see that people are forced to use hacks because of their 
editor. I know I was, with some editors.
I am also trying to understand how migo stays focused on his code when 
using these hacks.
Let's put aside the "must" features of editors, these are "musts" for me 
when I (_personally_) look for an editor, and that's because I've been 
looking for the perfect one and changed quite a lot of them in that time.
The current one isn't perfect, but it's the closest, for my criteria.

I am also trying to understand why migo thinks my auto-completion habits 
aren't effecient (or worse, how they make me lose focus from my code - 
which they really don't).

And usually that means: auto indent, auto complete.

Auto indent: this is a must for editors. This time I insist an editor 
must have this feature, and you should have it as easy to operate as 
possible (read: it should be transparent to you - you shouldn't even 
think of it, it should just happen).
I've seen a lot of code which isn't indented, or worse, semi-indented.
When you have to indent on your own, it's bad. That means you might get 
into a situation when you add code in a hurry (urgent bug fixes, happens 
to all of us) and forget to indent it.
Most editors make you type something to indent, and I chose one that 
does it automagically.
Most of the poorly (or not at all) indented code I've seen was written 
in these editors (without mentioning them - you should know if your 
editor is one of them).

Auto complete - for crying out loud, mistaking variable names can cost 
you time/troubles/hair.
Copy-pasting would also take time and would also cut my line of thinking 
(at least for me, _personally_, though I don't think I'm unique in that 
This isn't a must, ok, but I believe (stressing it again: _personally_) 
it would result in better code - so you should consider using it.

I just don't like the fact that people get used to a tool and then hack 
their way into that tool.
Switching editors is painful, I know, but I wouldn't continue using an 
editor where I (*cough*) have to background the window, open a new 
editor, find the variable, close that editor, fg, and finally paste 
At least let me split the window so I could stay in the same line in the 
bottom window (for example) and find the variable in the upper one, and 
then copy paste.
You will lose focus in that kind of thing, no matter how you look at it 
(or maybe I'm not thinking hard enough...?).

Losing focus IS Evil (why do you capitalize evil, btw?).

Again, your editor must make you be as productive as possible, help you 
generate good-looking (very well indented, which means readable) code 
easily, and give you all the features and tools to program easily.

Does anyone think Migo's approach of backgrounding the editor, etc, is a 
good one?
Working like I worked with pico (which is Migo's approach) is that last 
thing any programmer would (or at least should) want.

Also, what features do you find in your editor that makes you produce 
better code?


P.S: I find it to be only semi-offtopic because effecient programming is 
really important IMHO.
Gabor, let us know if we're really offtopic.
