Leaky Scanning protein sequences need to be arranged by likelihood of being made, not by length alone.
Rather than just displaying the protein sequences in the Leaky Scanning module as longest-first, they should be displayed based on the scores of their start codons, and the number of leaky stop codons present in them should negatively affect their position. They should also only be displayed up to their stop codons for that specific protein, not with any extraneous material thereafter unless their stop codon is leaky.
It should also be made clear which stop codons are leaky and which are not.
