Hello everyone!
I'm ReverieCode, a Community Manager from Fandom recently assigned here to provide assistance, or give any relevant update - today, I'm here for the latter :)
You may or may not know, but for the past few months Fandom has been performing different experiments with the Interactive Maps, such as adding a feature that allows users to track their personal progress interacting with the markers on a map. One of the previous limitations we had for the initial release was the storage of progress data, which was done via local storage in each user browser.
Starting next Monday May 27, we’re starting to save marker progress tracking in our own database, using Fandom accounts. This change would avoid anyone losing previous progress, and also allows for people to switch across devices while keeping this progress tracking updated. Because the data is saved in Fandom accounts, the feature is only available to logged-in users.
This should be an interesting update, since anyone using an interactive map (at any wiki with the progress tracking feature) to keep track of a game's collectibles they have by checking markers would then keep that progress tied to their account, no matter what.
If there's any feedback or questions for this, I'm happy to relay it to the people working on the feature. In general, maps continue to be worked on - with other ideas in the pipeline to make them more useful.
