Fair enough. It screams pre OS X NextStep to me, which is probably very much related to that. Chrome aside, the non-modern thing that jumps out at me is that you likely have a few more windows/dialogs/palettes/etc. you're working with in TclSqueak, where Komodo adopts a pattern of decorations on the side of a single window that cause additional panes to appear within that same window as you click them. I don't especially like that specific turn we've taken over the past 10 years or so, but that pattern of revealing hidden bits within one big window sticks out quite a bit even beyond the chrome to me.
