I have heard two explanations for drooping leaves on your plant. One is the plant was too dry a bit too long at some time. The other is the plant got too cold. Either way the condition does not go away. It is not unsightly tho, and some people actually like the droop.
Yellowing of new leaves can mean an iron deficiency. Repotting leaves plants a little wimpy, for a while. I think your plant is quite lovely, and you have done all the right things so far. There could be some expert tips you can try, but you have sure not done any harm. Good Luck and Welcome to the forum!
