LittleFS can be used (a choice for ESP8266 for now)

- To make and upload FS https://github.com/earlephilhower/arduino-esp8266littlefs-plugin
- Simply redefine SPIFFS to LittleFS
Changes are in src/SPIFFSEditor.cpp including the src/edit.htm
See ESP_AsyncFSBrowser and SmartSwitch examples

 ## SmartSwitch
-
-* Remote Temperature Control application with schedule 
-  
-  (example: car block heater or car battery charger for winter)
-
-* Based on [ESP_AsyncFSBrowser](https://github.com/lorol/ESPAsyncWebServer/tree/master/examples/ESP_AsyncFSBrowser)  example that uses embedded ACE editor 
-
-* Wide browser compatibility, no extra server-side needed
-
-* HTTP server and WebSocket on same port 
-
-* Standalone, no JS dependencies for the browser from Internet
-
-* [Ace Editor](https://github.com/ajaxorg/ace) embedded to source but also - editable, upgradeable see  [extras folder](https://github.com/lorol/ESPAsyncWebServer/tree/master/extras)
-
-* Added [ESPAsyncWiFiManager](https://github.com/alanswx/ESPAsyncWiFiManager) and fallback AP mode after timeout
-
-* Real Time (NTP) w/ Time Zones. Sync from browser time if in AP mode
-
-* Memorized settings to EEPROM
-
-* Multiple clients can be connected at same time, they see each other' requests
-
-* Authentication variants including [Cookie-based](https://github.com/me-no-dev/ESPAsyncWebServer/pull/684) idea
-
-* Used [this Xtea implementation](https://github.com/franksmicro/Arduino/tree/master/libraries/Xtea) for getting a fancier Cookie token
-
-* Default credentials **smart : switch** or only **switch** as password
-
-* OTA included
-
-* Use the latest ESP8266 ESP32 cores from GitHub

 ### Extras
-
 Additions to facilitate code modifications (for MS Win, similar can be done on Linux)
 
-**ehg.c (ehg.exe):** Tool to generate C-code array from file' bytes
+- **ehg.c (ehg.exe):** Tool to generate C-code array from file' bytes
 Based on [bin2array](https://github.com/TheLivingOne/bin2array/)  PROGMEM keyword can optionally be added.

 First 4 lines of source are ignored, then parses the 0xHH - formated bytes 
 until a } is found on separate new line.
 
 ### Tools
-
-[TCC : Tiny C Compiler](https://bellard.org/tcc/)  for **ehg** and  **rehg**  compiling on MS Win
-
-[7-Zip](https://www.7-zip.org)  Install 7z and use the included gzip as command line tool
