Hi Ofihombre - Happy New Year to you as well! :) I responded to your e-mail, but I figured I would go ahead and respond here as well. I definitely agree with you on this. Once I am mostly finished with the Undo/Redo system for the Map Editor (hopefully within a week or so), I am going to refocus my efforts onto these sorts of features that you mentioned in the coming months so I can get the engine better prepared for Steam Early Access. I'd like to get some basic "save game" functionality implemented as well.
Also, since they are making great progress with the new renderer for Godot Engine which RPG in a Box uses, this effort will probably also include some rework to make sure everything functions properly using the new renderer - which will hopefully open up some new possibilities around graphical effects/styles.
