The spell checker should limit the levenshtein distance based on the length of the searched identifier. More typos for longer names and fewer or no typos for shorter names. For example it doesn't make sense to propose 'b' when someone typed 'a'.
Currently the proposals are only based on the minimal levenshtein distance.
It would make sense to weigh certain edits higher than others, e.g. capitalization errors or interchanged letters are more likely than other typos.
