1. Start from scratch and redesign UI using the latest version of ExtJS 7.6. We have multiple applications with ExtJS 3.4-based UI (very interactive Single Page Applications with 100s of screens) that make the development of advanced UI easy and fast 
2. Rewrite/port existing applications to the new UI 
3. Improve documentation and education for best practices that we learned over the years but didn't always go back to refactor older code: use only asynchronous API for server communication, use only our APIs for accessing lower-level features of the underlying UI widgets, implement routing
