Thanks for changing that
What IMO is still tedious (but probably either intended for reasons I don't see or the old mechanic just technically no longer feasible) is
the restriction of only one upload possible per initial report (and for each more you need to edit the report one time). I tend to make my bug reports usually with not only at least one save file, but also often up to a couple of screenshots...and then multi-edits are a slight strain. Plus that it means that uploading can't happen while you type the report, but will start only after hitting the send button...not a huge thin for people with fast internet connections, but if you don't have one and try to load up a savegame that might mean that for quit a time the post is in transit and not finishing. That might some poeple think there is a technical problem with making reports, especially if they are used to the old method. Sure, you can circumvent also by just filling the 2nd post with the screenies, but I always hesitate to make such double posts.
As said, my gut feeling is that this likely can't be changed, but anyway I'm giving you my feedback here in case it is useful for something
