My initial adaptation of LinkuisticsUI to enable it to load in VW 7.7 (sep09.3) has worked. It still works in 7.6. Not yet available in the public store, but soon.
It has some visual glitches - font baselines seem slightly different, the splitters are unusably slow, the tab control overflow arrow mechanism has changed, and the icons don't play nice. I'm planning on retaining my icons for the lists, except maybe the package tree. Primarily because matching the new icons is an unrealistic amount of work. This is the main reason my iconography looks like it does - people without artistic ability/tools can extend my icon set without it looking like a dogs breakfast. This seems to me to be an absolute requirement in a user-extensible environment such as Smalltalk, which isn't feasible with the more usual icons that VW used/uses. I coincidentally find the less in-your-face design more attractive and usable.
