* Give Tsangan layout a real Fn2 layer
* Disable mouse keys to work around qmk#8323
I don't actually use this feature, so there's no reason for it to be
enabled anyway, and it seems to cause spurious wakeups on Windows.
* Enable link-time optimization
* Make RGB static gradient ranges shorter
* Shift Quefrency media keys to the right
* Shift KBD67 media keys to the right
* Move some 60% keys from function to adjust layer
* Set "extra" Lily58 keys to browser back/forward
* Remove Instant60 EEPROM hack after #6968
* Remove unnecessary bits from macropad keymaps
* Update KLE images
* Move grave/tilde and backslash/pipe to left hand
* Shift media keys to be aligned with home row
* Update KLE images
* Mention new media key location in readme
* Turn off a couple more features for explicitness
* Turn off more unnecessary features by default
* Double TAP_CODE_DELAY due to more media key issues
Even with this change, some of the rotary encoder turns on my BDN9's
volume knob still seem to get dropped. It's possible there's something
wrong with the encoder itself. (Maybe the TAP_CODE_DELAY actually causes
QMK to miss an encoder turn? Unclear.) The other knob (backlight
brightness) works fine, FWIW....
* Restructure userspace config.h a bit
* Hack around Instant60 Via EEPROM conflict
Remove this when #6589 is fixed for Via boards.
* Add backlight breathing and (EEPROM) reset to BDN9
* Add keymap for 9-Key macropad
* Switch Quefrency from flaky I2C back to serial
* Lower mouse wheel speed on Quefrency slightly
* Migrate common settings to userspace
* Enable Bootmagic Lite for consistent reset to bootloader.
* Turn off some undesired features across all keyboards.
* Remove EEPROM reset keybinding from all keyboards since Bootmagic Lite
also does an EEPROM reset.
* Set backlight and underglow increments consistently across all
keyboards since lots of them like to override the deafults.
* Set mouse keys consistently across all keyboards.
* Update function layer keymap images
