I would like to do this, if only I was able to do all :)

I know this, but I've only setted tabs as 2 spaces (loading and writting) as
you suggest into yam dev guide, in fact I've left only changes which fix
some wrong tabs probably don't seen by your editor :)
In fact thing like this:

// some own usefull MUI-style macros to check mouse positions in objects
-#define _between(a,x,b)    ((x)>=(a) && (x)<=(b))
-#define _isinobject(o,x,y)     (_between(_mleft(o),(x),_mright (o)) &&
_between(_mtop(o) ,(y),_mbottom(o)))
-#define _isinwholeobject(o,x,y)    (_between(_left(o),(x),_right (o)) &&
_between(_top(o) ,(y),_bottom(o)))
+#define _between(a,x,b)           ((x)>=(a) && (x)<=(b))
+#define _isinobject(o,x,y)        (_between(_mleft(o),(x),_mright (o)) &&
_between(_mtop(o) ,(y),_mbottom(o)))
+#define _isinwholeobject(o,x,y)   (_between(_left(o),(x),_right (o)) &&
_between(_top(o) ,(y),_bottom(o)))


it shows as I fix a wrong indendation :-)

if you want I could do this, but you have to tell me how download/cancel my
changes with svn so I don't do this with hand ;-)

I want insert real \t support to TE MCC, I've just a proper custom Text()
function to right translate on the fly \t into n spaces (to use instead of
plain Amiga Text() function), it works on TextEditorMCC, but when I move
cursor with arrow buttons on a line which has a translated \t then that
line is updated by cursor as my past translation of \t was not done. So,
for example with topaz font, line with a \t=4spaces is rewritten(redraw) by
cursor considering \t as 1 character (because topaz draws \t as 1 rectangle
char), and thus text is bad drawn.
I've tried to modify SetCursor(), LineCharsWidth() functions, but I've not
solved this issue, probably because I've no understand as TE rendering
functions work (or if they are really the TE's rendering functions), so I'd
like to receive some suggestions about where I should modify sources:-)
