Now, personally speaking, I find this very weird indeed. But some people might like the idea, so I thought it was worth mentioning.
You’re probably already aware of TextMate, which like most text editors eschews a lot of the user interface stuff you see in other apps. There’s a window, with text in it, and there are many many commands you can use, but there’s not much to see: there’s no toolbar.
SuperMate doesn’t add a toolbar, it’s more like adding a skin. It tinkers with TextMate’s panels and tabs and a few other things like the web preview window, and just Leopardizes them a little.
Personally, I think TextMate’s just fine as it is. But if you’d like to see it a bit more, um, purple, maybe this will be of interest.
