Some hints are elaborated :
The chart of chronological Development of Devanagari
Script from Brahmi onwards to now, shows :

-- the use of Hraswa 'i' (small i) was after the
consonant, and put at above only.
-- there was only one form of 'r', which was with
'kana', (present form of refa came after corrupted
use) which represents all the forms of r ie ri, hri,
rii, ra, reph, ru, roo, ttra, tra, etc.
-- the Chandrabindu, Anuswar and bisarg were after the
o, ou, Vowels in sorting order. 
-- In BarahKhadi - (i.e. like : ka, kaa, ki, kii, ku,
kuu, kri, kli, ke, kai, ko, kou) were used.
-- The Anuswar, Chandrabindu, and Bisarga may come
with any of these BarahKadi consonants+vowels as (kan,
kaan, kin, kiin, kun, kuun, krin, klin, ken, kain,
kon, koun)...(kah, kaah, kih, kiih, kuh, kuuh, krih,
klih, keh, kaih, koh, kouh)...
-- The basic sounds (characters, ie
Vowels+consonants+matras) were limited to 49, called
Marut, Bijakshar or Bijamantra, each denotes a DEV or
DEVI.
-- The Ya, Ra, La, Va, characters are derived from
the mixing up of vowels
ya= i+a, Ra= Ri+a, La=Li+a, Va=u+a
-- The 3 types of S were have clear definitions
-- The ka, anga, chha, tta, ttha, dda, ddha, da, pha,
ha, all were Kanakar, i.e. the absence of kana makes
pure consonants = consonants with halanta = half
characters.
-- The Panini's Ashtadhyayi, Siddhanta Koumidi etc.
referes much elaboration at sentence/syntax level.
-- Each and every sound of any languages/boli of the
world can be written in this script and can prounced
back 'as it is it'.
-- The frequecy of sound, pitch of sound, volume of
sound and Tone of sound also taken care with the 
Udatta, Anudatta, Swarit etc. 
--The Avagraha for reprentatation of time slice of a
vowel has special place.
-- The Musical Saptak/rhythm also implied and
represented.

-- If encodings developed on this Moola Devanagari in
some revised form according to the structures of
compunting,
-The future sound-based computer input-output
system(avoiding keyboard) and NLP may work fine on
basis of it.
-Internet telephony may be 1000 times faster.
-World voice comunnication will be easier, cheaper and
thousand times faster.

It is too complex and still can not provide perfect
sound/dhwani-based auto sorting order (as per the
frequency and pitch of the sound)

I am trying to develop a presentation in powerpoint
slides to explain above points with proper
pictures/graphs.
