I’m personally of a mind that the link to the old uploader shouldn’t be there, but I rarely use projects thus I’m not sure my opinion counts for much here. So I’d like to get opinions about the utility of the current set-up.
I don’t think we can have the “Add Observations” button on a traditional project take one to the current uploader and have that project selected, so that’s not an alternative.
FWIW I prefer the new uploader. Ideally it would preselect the project if called from a project page, but if that’s not possible then oh well. I’d go out of my way to avoid the old uploader.
I’ve always found that button confusing. What I want to do when adding observations to a project is to go to my existing observations and select which ones I want to add, not to create new observations from scratch. So I’ve never used it. But perhaps the button makes more sense to others?
