Weird. The picture is off in my browser. I didn't even notice. That looks amazing!
As to the ethereal Quest Editor I have some basic thoughts:
-Make sure it supports an infinite amount of objectives. I am currently averaging 5-20 objectives in my current efforts. The Labyrinth is close to 35 I believe.
-Please make the UI a drop down sort of deal where we can add a game modifier that pops in under the objective with all the requisite parts. Having each objective show a massive list of all the possible things an objective can do makes the UI scrolling painfully long and confuses the hell out of people.
-Objective 0 and objective 1 is confusing. Keep it how it is, but make sure the player can easily tell that the game starts at 0, not 1.
-Please get free with drop down box lists for items and monsters to be added. The more we can choose from a list, the faster things will go.
-Choosing the goodie hut and such would also be smart to be chosen from a list.
-Some things need to stay in highly custom format, though. Encounters need to have lots of room to choose the level and equipment of those units.
Just some basic ideas. I look forward to a final word on this as it would give me some modding competition from other users.
