 TBA: Should the app be treated as a clock face app?
 
+## Potential Improvements
+
+- Tweak size of icon vs text box.
+- Add backgrounds library and use clockinfo drawBorderedImage.
+  - should it be a dependency or should there be conditional implementation where it's alright to go with or without?
+- Could the clock clkinfo icon be made dynamic to show the actual time. That would be neat.
+  - either native implementation in `bigclkinfo` or through `clkinfoclk` app dependency.
