for what particular reason?

i've got 200 threads of execution in my fcgi module, how do you intend to eval that?

> Multiple editors with just one function in it. Show code in an "area of concern" not just in a file.

kinda interesting, but won't work really. usually you have quite a bunch of code, 100-200 lines in a function which is a regular business. put 10 of those on the screen and you've got enormous unmanageable pile of crap.

> The coding environment can show also results, app windows, graphics, other tools.

any specifics? but yeah, i must admit you can put fancy widgets on window panes lol

> Can save the configuration of the above. WOW!
