+/**************************
+ * QMK Features Used
+ **************************
+ * RGBLIGHT_ENABLE
+ *  - Adds layer indication via RGB underglow
+ *  - see the `layer_definitions` enum and following _*_HSV #defines
+ *
+ *
+ *
+ **************************
+ * Custom Feature Flags
+ **************************
+ *
+ * TWSCHUM_TAPPING_CTRL_PREFIX
+ * - Adds feature that makes sending nested sequences of C-a, C-b[, C-b, ...]
+ *   as simple as C-a b [b ...]
+ * - Not necessarily super useful outside specialized nested tmux sessions,
+ *   but it was a fun state-machine to build
+ *
+ * TWSCHUM_VIM_LAYER
+ * - Fork of xtonhasvim, adding vim-emulation
+ *
+ * TWSCHUM_IS_MAC
+ * - Flag for handling media keys and other settings between OSX and Win/Unix
+ *   without having to include bootmagic
+ *
+ **************************
+ * Features Wishlist
+ **************************
+ * use VIM_Q as macro recorder!
+ * Dynamic macros
+ * Leader functions
+ * Uniicode leader commands??? (symbolic unicode)
+ * Mac mode vs not: -probably bootmagic or use default with dynamic swap out here
+ *    KC_MFFD(KC_MEDIA_FAST_FORWARD) and KC_MRWD(KC_MEDIA_REWIND) instead of KC_MNXT and KC_MPRV
