Scratch 3.0 has many problems to fix for one, many people in the collabartion communityt are having a hard time using Scratch 3.0 because the remix tree was removed when Scratch 3.0 was launched. A solution to fixing the problem is to bring back the remix to help solve the problem the MAP community is having.Also, many people like "_Plush_Trap_" having said the new scratch is more laggy,so it will be a good thing to fix that as well, and lastly audio editing has changed this wil be big problem for the meme community who like to edit audio around. The audio editor now is one big thing instead of you having to scroll. Which makes editing some small parts of songs very diffuclt.
