GD got a roadmap on Trello:
But, at the moment only Victor and 4ian can add "Ideas" that may going to be implement at some point in the future.
I would think any feature requested here on the forum that seems reasonable and realistic would make it to the Trello board as an "idea" but it is not the case and I'm not certain if it because the features we are requesting is found to be not reasonable or realistic by 4ian or he may just miss it, too busy to read the forum because in most cases we receive no reply from him and 99% of the time the request just won't make it on the Trello board and we just left with the question all the time, "is my request has been considered at all?"
So, how about that if we would replace this Feature request forum with Trello completely?
We (anyone) could add suggestion on Trello, describe the idea and people can vote to be added and if 4ian find it reasonable and realistic (doesn't require complete rewrite of the engine), it would be moved to the "ideas" tab by 4ian or Victor.
Of course I don't expect any feature to be worked on straight away when it make it in to the "Ideas" tab, but it would be a clear indication of that the feature request is seen and considerer by the devs and found to be reasonable to be implemented at some point in the future.
Also, when 4ian got the time but happen to have no idea or plans what to develop next, he could pick something based on the votes on Trello not just pick something random.
4ian seems to be active on the Trello board, that's why this request. He doesn't need to start a conversation and explain anything if it something he doesn't want to do, he just simply need to move the request from "Suggestion" to "Idea" to make a clear indication of that, the feature is considered and found to be realistic.
If something found to be unrealistic he can even flag the ticket something like "Trash" to make it clear the decision without need to explain anything.
