Spoiler:

Increase TOC level indentation and fix extra indentation bug:
  - Enabled: yes
  - PatchGroup: TOC Indentation
  - Description: |
      The space indented Table of Contents levels are quite hard to see, as the
      difference is almost too small to easily notice. In addition, this fixes
      the bug where all TOC entries are indented by 1 level extra.
  - BaseAddress: 0x8B2FD2
  # Clear out existing instructions with NOPs
  - ReplaceBytes: {Offset: 0, FindH: 07 F1 0C 0B, ReplaceH: 00 20 00 20} # put string address in fp
  - ReplaceBytes: {Offset: 4, FindH: 42 00, ReplaceH: 00 20}             # shift level by 1 (multiply by 2) into r2
  - ReplaceBytes: {Offset: 6, FindH: 4F F0 20 01, ReplaceH: 00 20 00 20} # set r1 to 0x20 (space char)
  - ReplaceBytes: {Offset: 10, FindH: 58 46, ReplaceH: 00 20}            # put fp in r0
  # Put new instructions
  - ReplaceBytes: {Offset: 0, FindH: 00 20, ReplaceH: 40 1E}             # decrease level by 1
  - ReplaceBytes: {Offset: 2, FindH: 00 20, ReplaceH: 02 22}             # load multiplier into r2
  - ReplaceBytes: {Offset: 4, FindH: 00 20, ReplaceH: 42 43}             # multiply level, result into r2
  - ReplaceBytes: {Offset: 6, FindH: 00 20, ReplaceH: 20 21}             # set r1 to 0x20 (space char) 
  - ReplaceBytes: {Offset: 8, FindH: 00 20, ReplaceH: 05 A8}             # put string address (sp+20==r7+12) into r0
  - ReplaceBytes: {Offset: 10, FindH: 00 20, ReplaceH: 83 46}            # save r0 into fp
  # Replacement value (multiplier):
  - ReplaceInt: {Offset: 2, Find: 2, Replace: 6}

Perfect! Now everyone can have the exact indent they want.
Great collaborative work geek1011 and GeoffR, karma to you both!
