- WiFi Connect app is now hidden by default, but accessible at the bottom of the WiFi Manage app when WiFi is turned on. - WiFi service now turns on WiFi when calling connect() and WiFi is not on. - Removed `blocking` option for `service::loader::startApp()`. This feature was unused and complex. - Various apps: Moved private headers into Private/ folder. - Various apps: created start() function for easy starting. - Added documentation to all TactilityC APIs - Refactored various `enum` into `class enum` - Refactor M5Stack `initBoot()` (but VBus is still 0V for some reason)
