- Tons of data loading optimizations. Animations should be smoother now.
- Switched tile to card. (Not sure if it's better, let me know if you prefer the old look)
- Fixed a bug where the same entity can only exists in only one group at a time.
- Pre sorting of entities during bootstrapping. (sensor, followed by device tracker, remaining kind of sensors, lastly by domain, alphabetically)
