RE: [imp-dev] Use of org.eclipse.zest in pdb.ui

["Ed Willink" <ed@xxxxxxxxxxxxx>]

Hi

Is there a significant unskilled user base that needs to not have GEF?

There are numerous projects that depend on GEF so surely everyone has it.

Requiring only half of GEF is more confusing than requiring all of it.
