+## Immediate ##
+### LLAP sensor message handling ###
+ - remember timestamp (when was the last message received)
+ - allow for "disabling" the display/processing the messages?
+ - refactor variables: make one object for one sensor
+ - do something about STARTED/AWAKE/SLEEPING messages?
+
+## Eventually ##
+ - Implement Log section (last couple of things pulled when connected, then each time a message comes, add it to the log locally)
+ - Phone-friendly version of the site
