Many thanks for your effort 'Custodian'.
One of the annoying things (bugs ) that I saw in many applications like this (nelisquare, Yappari and some others ) is typing with second characters of keys (shift+keys) for some languages like persian, arabic, hebrew, etc., which is not supported. Imagine you want to type the character "چ" which is assigned on "P", or "گ" which is on "O" as the shift (2nd) keys, but it types Latin "P" or "O" instead. So we should use ukeyboard instead, but the application ("nelisquare & tweetian" only) closed unexpectedly (now expectedly ) because of that "known-background-bug".
