I agree, we need to ease the creation of custom themes. One important
step will be the RAP Theme Editor [1] that will make it into the
incubator in the next weeks.

The RAP Theming defines the default look and feel of the widgets, but
not their layout. RAP provides a so-called "interaction design API" [2]
that lets you define the position of certain parts of the UI like menu,
toolbar, perspective switcher or stack presentations. We also provide
two example implementations.

There are two declarative UI approaches in e4, XWT and TM. The workbench
layout will be defined by exchangeable renderers. All these things
should also work with RAP. I'd suggest you discuss your ideas on the e4
mailing list, since everything that goes beyond default widget styling
should be available on all platforms.
Best regards,
Ralf
