The way that variables are sorted in snap! is different depending on where you are trying to select them from. For example if you are trying to select a variable in a set or change block, you will get the variables from oldest to newest going down:
This is different than the behavior in the pallet where they are sorted alphabetically:
My request would be to have these be sorted in the same way, so you don't have to search for the name of the variable you want to use after just putting in a reporter from the pallet. I find the alphabetical sorting to be very helpful, especially when creating similarly named variables, but I can see that there are reasons to sort it the other way as well.
