Yes, that's correct. We thought, what do you do after you download the source? Well, there's not much else to do than open it in Greenfoot, so the "Download source" and "Open in Greenfoot" buttons seemed somewhat redundant.
As you correctly say, the one button now does both.
Sounds great ^^ Is the new version of Greenfoot going to follow the gallery upgrade?
Yes, it will follow soon. We are still in testing (and still finding small issues). It could be another week.
Yay ^^ I am so excited for the newest release :D Can't wait for it to come out!
