Never modded but I'd like to give an opinion, the triple jacks starting at 00:13:403 (13403|2) should likely have the last note in a different column
the last note on the triple jacks have the same sound as the ones on the jack so ill leave as is for better representation
as a side note, netzoid (https://osu.ppy.sh/users/25673755) has a useful guide on modding on his me! page, you can find it under "Stuff I made"
