I looked at both screenshots, and aside from the dark theme, it's not clear how the Komodo screenshot is different. They both show a bunch of windows that presumably allow you to navigate files and classes, and the code window offers syntax highlighting. Sure, the window style is different, and the fonts too; there's more color in the non-coding windows on the Komodo side. All right, design-wise the Komodo screenshot feels more modern. However, my take on "modern" is that the authors of the TclSqueek were thinking more at function than form. I can't speak about that one with first hand experience, but I talked with Smalltalk developers, and they think the Smalltalk environment is still unmatched. If that is the target that TclSqueek tries to emulate, then it is "modern".
