yet another spelling reform proposal.
capital vowels are long, lowercase short.
bat -> bat    bait -> bAt
bet -> bet    beet -> bEt
bit -> bit    bite -> bIt
bot -> bot    boat -> bOt
but -> but    boot -> bUt
some extra vowels use other letters
bout -> bWt   book -> bVk   beaut -> bYt
when a sound that isn't a vowel is held, it is capitalized
bird -> bRd      tackle -> takL    
taken -> tAkN    system -> sistM
finally, several digraphs are replaced
thick -> Tik    then -> Den
ship -> Sip     chick -> Cik
sing -> siG     loch -> loX
