+- RLL encode images:
+  - 1 cntrl byte
+    - bit 7=0: bits 0-6=number of normal bytes following
+    - bit 7=1: bits 0-6=number of repeats, in this case the repeated byte follows
+
+- encoding:
+  - buffer
+  - bytesInBuffer
+  - loop
+    - startOfRepetitionWithMoreThan2Bytes?
+      - yes:
+        - add buffer to result with preceeding CNTRL byte
+        - reset buffer
+        - add CNTRL for repetition
+        - add repetition byte
+      - no:
+        - add current byte to buffer
+        - buffer contains 127 bytes?
+          - yes: 
+            - add buffer to result with preceeding CNTRL byte
+            - reset buffer
+
+
+- new classes:
+  - button
+    - move touch code there
+  - flashingLabel
+    - use timer to blink/flash label, e.g. when values change
+- widget:
+  - font
+    - use ressourceId instead of direct pointer
+    - store font in ressources
+
+
+- sensor watch:
+  - SDRAM vars:
+    - nodeAddr
+    - variableId
+    - currentValue
+    - threshold yellow
+    - threshold red
+  - widgets:
+    - title (label)
+    - image (imageView)
+    - value (flashingLabel)
+
+  - routines:
+    - setValue()
+
+  - routines in app:
+    - onMsgReceived:
+      - filter-out reportValue
+      - filter-out setValue msgs (to select sensors)
+
+
+
+- imageViewer (use code from testWin)
+- generate bigger images (96x96 px)
+  - cloud (light blue)
+  - temp
+  - humidity
+  - light
+  - window_open
+  - window_closed
