Things are progressing well and it’s very likely that Workshop support will be made public in the coming week.
The one technical hurdle we discovered is that GDT.getRelativePath() does not always return a correct value but there is an easy workaround and we updated our guidelines for this.
At the moment we have 13 mods in the Workshop. @alphabit and @SirEverard’s mods should also make an appearance soon.
I think the main thing that would make the Workshop items look better is if modders use the ability to edit their workshop item pages, editing the description of their mods and making use of the ability to add further images, or even videos.
I expect that there will be a sudden influx of mod-users once we release Workshop support and naturally players will gravitate towards mods that are presented in an attractive way.
