> It is old Sun technology that Sun abandoned to work only on Java

Not exactly true. Tcl/Tk was not invented at Sun, although Sun did fund its development for a few years by employing its author John Ousterhout.

But, I agree with you that the UI look is outdated, and needs some touching up. Every time this issue is brought up, the Tcl folks point to the "new" theming capabilities that were added in v8.5 (or perhaps v8.4?). I haven't looked at theming in Tcl to make an opinion.
