Thanks; I think only 6cdf7cc and d4e7441 are non-stylistic in nature, and I don't think the others are necessarily "improvements" over the current state. Could you remove all commits but those two?

Commits 11d8431, a5d45f2, and 7ef5d12 have been reverted. However, 6802212 was kept because it ensures proper verb agreement by using are instead of is in order to accurately convey that the vast capabilities (plural) are the distinguishing features of KMonad.
