I was looking at the new settings in the 64 bit content tool and was disappointed to discover we can only set values that are already there.
I know you don't want chaos in the filters (redundance and so on) but is this really the best way? To ask the developers everytime we want to add a new manufacturer, operator or even the name of the vehicle type? Unlike in OMSI, there're only a few people who can make their own vehicles (anyways we cannot modify already built vehicles), so I don't think it would lead to chaos if we could add new regions (cities), operators, etc.
At least at the region/operator/type filters it'd be nice to add new list elements by ourselves.
Also, in the description (Manufacturer menu) you cannot scroll with the mouse, can only move with the cursor buttons.
Another idea, what if it'd be possible to add multiple descriptions, filtered by language? Like, you could add an english description and another one in another language (with a tick box "English description" in the add vehicle menu for example). I mean since I build hungarian tram(s) it'd be nice to add hungarian descriptions as well but I guess other people from different countries wouldn't really appreciate that.
Also, what if in the main game at selecting vehicles, there was thumbnails instead of lists? Like, you select the manufacturer, and after that you see thumbnails and not a list of types. Maybe, showing the type (name) if you move the cursor above the thumbnail or something like that. Or it was selectable, to see a list or thumbnails.
