All your discussions sound very interesting. I know I'm not really
part of the decision makers here but my 2-cents from a readers point of
view.
I would suggest that GNUstep applications run in Étoilé run with the
old GNUstep theme, not Nesedah, to provide a visual clue that they
are not full members of the Étoilé environment.
There is some validity to this (things that work different should
appear different), but I would personally rather design a new theme
than use the GNUstep one. Something that was a bit more integrated
into Nesedah (just as modern), but maybe using a different color. Or,
maybe not...
In my point of view ( a biased mac user ) that would be like running
OS9 apps in OS X. And what Jesse said would be like like having
brushed metal apps and regular Aqua apps. This is purely what I imaged
it to be while reading this, but I personally think what Jesse said
makes more sense only if there is even a need to differentiate. My
reasoning for this would be because I'm assuming all the etoile
specific frameworks work with regular apps too? (like gnustep apps can
use DataKit and other *Kit for etoile?), so why even differentiate? It
should be obvious what is legacy and what isn't just by the way you
interact with it, right?
