Missing Open With for Plug-in Dependencies
For normal files in the Package Explorer, the context menu offers a default "Open" and a flexible "Open With"; good.
For Plugin Dependencies a much smaller context menu offers only "Open" which is unhelpful when the default editor is not what is required.
Suggest review the context menu filtering so that more offerings are provided.
Diito, binary files
and the GIT history
have limited "Open With" flexibility.
I had another idea; offer a reopen with in the 'wrong' editor. I see that most platform and Xtext editors already have an internal "Open With", but unfortunately not EMF generated editors. Surely the AbstractTextEditor should enforce an "Open With..."
The original enhancement of an outer "Open With" still applies since sometimes the default editor can have very bad consequences; maybe even a crash. (Particularly a Bad Compare editor.)
