how is a lack of engine development relevant in making an addon
You are an idiot. You start a project that begins looking good and working (in some ways) and then you stop making it and say you want to discontinue.
I don't see the point in even asking peoples thoughts on this. Mostly everyone who's still playing this game wants this to be completed.
Because you dont have as much of a variety of things to do while making an addon if the engine is never updated.Aka it becomes redundant
Definitely keep working on this. It will be very convenient, just as RTB was. Also, change the poll to this question.
