When or will a feature be added that is in he Votebox?
I am waiting to become a premium member until the feature described in "creating a new project by duplicating an existing one or by copy and paste" in the votebox is added. Is there plans to add this feature and if so when do you think it may be added?
there is no particular threshold on how many votes a feature request needs to have before it will be implemented. Most of these requests eventually will, though.
Although we can't give you a time frame on when this feature will be implemented, it certainly will as it would be indeed very useful.
