feature: add bigraph statistics and practice mode
Often the simple metric of "wps" for each key is not detailed enough. For me, how fast I can type a specific letter is substantially dependent on the letter before it. For example I have quite some trouble correctly writing the S in "asked", while "stars" is very easy.
I would like to have an option to see which bigrams are troublesome for me (besides that anecdotic evidence). And then I want to specifically train those, so in short: exactly like the normal practice mode, but for bigrams instead of single letters.
totally agree with this! Trigram would also be useful, as introduced in carpalx and mathmulticore project. There usually the trigram used ignores the space character, but I think it is important to take the space into account, because space itself is a key that needs to be pressed, which then affecting the performance of the next or previous char.
