Hi Nuge,
I appreciate your feedback and understand your disappointment. Let me give you some insights into our development process.
Version 2.4 was released in October 2018, just like it was planned. Now we are releasing 2.5, containing lots of smaller improvements for all CADs, as well as the material editor for Rhino. We believe that this release brings a lot of value to all our users, even though the material editor in ArchiCAD is still missing.
Why does the Rhino plugin have the material editor? Because we had to start with one CAD - and the Rhino plugin was released in November 2017 while the ArchiCAD plugin was released only 7 months later.
We actually did plan to include the material editor for ArchiCAD in the 2.5 release as well, but priorities change over time (some other features become very important suddenly).
In the end, we were confronted with the decision to either remove the ArchiCAD material editor from the 2.5 release or delay the 2.5 release even longer. We decided to deliver the bugfixes and improvements to you as soon as possible.
Sorry if my words have been unclear to you in the past. It is scheduled for 2.6. We have planned a scope of features for 2.6 which does include the asset editor for ArchiCAD. However, being scheduled is not the same as being done. I can't promise you when the material editor will be integrated, but we're trying our best to make it happen.
