- sounds and option for verbal counting
- save/load rhythmic composition to/from file system
- divisions of a beat
- option for playing beat/ring in separate speaker/earphone of stereo output
- dark mode (Android for sure, maybe desktop)
- option for blinking of background during tick
- icons for menu
- skins: classic, digital, contemporary and that trivial of course remains
- maybe a few sounds more, i.e. digital, high pitched
- [Android] incoming call locks sound but doesn't lock pendulum = not synchronized move and sound
- some sounds are simply not acceptable - remove them (after some pool)
