@izeman in short, there is no update for this feature at this time. It is still something we want to do in the future, at least the on/off screensaver part of it.
For any idea, we let community to vote on it regardless, since some features might be infeasible from feature-set perspective, but might be worth it if there is a great need from the community.
Generally, I totally understand the desire to get more detailed status on any given idea, but it is hard to make these details public in a fluid development environment.
Publishing of roadmaps or any other forward looking plans varies from company to company, but majority choose to not them public. Inevitably any statement about future development is considered a promise by someone. So it would be unfair for us to make any promises that we canāt honor in the future.
I would always encourage any user to purchase license for the app at the time when they are happy with existing functionality when using free version, or if they want support any future development in principle.
