Haven't looked in game yet so these apply to the web version include any required DLC - this should include base routes, additional loco DLC or expansion packs etc. Unable to tell from the screens right now which loco or version of each loco is required On scenarios put in length of time of scenario and a difficulty rating, similar to the workshop on TSC I'm sure I'll add more, but feel free to comment and I'll update
These are some lovely suggestions. What I also like to see is that we are able to edit drafts via the website.
Having required DLC listed would be great for backend/server-side, so we wouldn't have to rely on the creator to put that stuff in, and especially for that to show up on the website, since DTL doesn't know what I own to tell me if the livery/scenario is usable for me. If you can't automate this, at least add more tags so that creators can select the DLC used as a tag. Also, please please please make tags searchable!
Easily done when the item is created. The scenario editor or design editor could include them as tags at that point.
