Coda is an elegant and well-designed program offering web developers a great environment to develop dynamic applications. I especially appreciate the ability to render ExpressionEngine pages directly in the program, real-time without needing to switch to a browser. It's stable and has most of the core features I like to use.

That said, it has some serious deficiencies. The most serious is that it chokes on large pages of a few thousand lines. That shouldn't happen in software that prides itself on being the next generation text editor. I can open a 66,000 line file in BBedit, complete with syntax coloring in about 1 second. In Coda, that same file takes about 1 1/2 minutes to open and, once open, scrolling is nearly impossible. This one problem limits it's usefulness for me and makes me keep my BBEdit in the dock. Related to this problem is extremely slow syntax coloring. There is a noticeable delay when loading even small files before syntax coloring is done and this becomes quite annoying after a while.

I could become a real Coda fan and even make it my exclusive text editor but it needs open large files in 1 second not 1 1/2 minutes. Inexcusable.
