- This update brings a full visual overhaul, with new icons, new buttons and color schemes. Memorión now looks very sleek!
- I also further reduced the number of functions of the Beginner mode to the bare essentials for learning and the Advanced mode has been removed (the user mode icon now just toggles between Beginner and Expert)
- Long-tapping on items now switches to selection mode (according to Android standard)
Version 5.21 fixes a few bugs of the mayor release v5.20.
