I'm very impressed with Graphiti.
Most I like features are:
* Modeled View: PictogramElement and GA. (SVG Export)
* Simplified as Feature Context from All complex GEF things (Tool, EditDomain, EditPart, EditPolicy).
* Declarative Approach. (Incremental Development)
* Many automated feature against of EMF model.
I created commercial GEF plugins for 3 years.
GEF is relatively complex, It's big deal to training my team.
Graphiti is really good alternative solution.
But I have some worries for now:
* Is it really unnecessary to access native library? (likes GEF API)
* I couldn't not find a way to show more appropriate feedback to user.
* Undo / Redo may update pictogram elements which are invisible area.(IE: other drill down context, not in viewport) Can I highlight them or select them?
* SVG Export feature seems not work well with Non-English Text GA. (It was rendered as a image which have little bit broken, with English Text GA, it rendered as SVG Text element)
* Direct editing (F2) works with only selected PE which is located under mouse pointer. Using mouse makes user get slow on their job. Can I change this behavior?

Graphiti aims at hiding the underlying library; although we currently only
support GEF, we have the option to replace it with another graphics library
in the futire, e.g. JavaFX. We allow to embed native GEF shapes into a
diagram and have opened ther dedicated APIs to directly access the layer
below. But the rest is emcapsulated on purpose. Just let us know spots were
it hurts and we will check and try to open up if needed.
* I couldn't not find a way to show more appropriate feedback to user.
Could you go into some more details here? Which kind of feedback would you
like to give to users?
* Undo / Redo may update pictogram elements which are invisible area.(IE:
other drill down context, not in viewport) Can I highlight them or select
them?
DiagramEditor offers a selectPictogramElement method that allows that.
* SVG Export feature seems not work well with Non-English Text GA. (It was
rendered as a image which have little bit broken, with English Text GA, it
rendered as SVG Text element)
That seems to be a bug. Would you open a bugzilla for this?
* Direct editing (F2) works with only selected PE which is located under
mouse pointer. Using mouse makes user get slow on their job. Can I change
this behavior?
Hm, if that's the case, it also appears to be a bug. Would you file that as
a bugzilla as well?

For instance, Consider OrderedLayout or GridLayout in GEF.
When user create or move entry element,
The Insertion Indicator needed to be shown.
I think something likes below will be needed. (not deep thinking)
public interface IFeedbackFeature{
- canShow(IContext)
- showFeedback(IContext)
- hideFeedback(IContext) // may be automatic removing using EMF ChangeRecorder against of Pictogram.
}
I think most important entry points are creating and moving.
So Selection Tool should have to be updated to support this needs.
