The code makes use of the WiFi library This library allows you to control the motors in a non-blocking way and allows you to control more than one motor at a time. The OTA Web Updater allows you to update/upload new code to your ESP32 using a browser, without the need to make a serial connection between the ESP32 and your computer. I've tested this with ESP-IDF rather than Arduino, and I believe the binary increased by about 300KB after enabling Bluetooth! It has some dependencies, and by just enabling that, you are adding those too. 2. This is possible since we can call IDF APIs from the Arduino core, pretty much like we do to use FreeRTOS in this environment. Some ESP32 Servo libraries only support a limited number of motors, however, ESP-IDF Programming Guide . move(0,0,0,1) (Scroll left) and bleMouse.
