Kalk is a beautiful Plasma Mobile application developed by @EspiDev and @hanyoung. I think it is near perfect for replacing Kcalc the current kde calculator. Feature missing are:
- various modes: scientific, statistic and numerical mode offering more advanced functions and constants
- Better layout on a larger screen (or even better add a max-width and max-height to the main window)
But Kalk also provides many new functions:
- An history of all the past calculation
- A unit convertor
