In the previous version, I found it quite useful to be able to expand the code boxes horizontally. It made longer macros easier to read (each line of code being on its own line, as opposed to wrapping to the next line). - If we could get this back one day, that would be great!

Love your work Tim. No rush on this one. :)

I need to hook this somehow. http://wowprogramming.com/docs/scripts/OnSizeChanged

Being able to resize/expand the box vertically would be nice too, for larger resolutions (i'm at 1920x1080, personally and it's a bit small of a window to work with). Is it possible to put a click/drag handle in the bottom right corner?

Done and Added.

When resizing there is a bug where if you resize on a macro page it can mess up but if you resize initially on the Config window it behaves.
